- MakaleAçık Erişim2022Investigation of environmental and time depended effects on historical masonry minarets by vibration test; [Tarihi yiǧma minarelerde çevresel ve zamana baǧli etkilerin titresim testi yardimiyla incelenmesi]
Yanik, Yusuf; Türker, Temel; Çalik, Ismet; Yildirim, Ömer
Historical structures are important pieces that connect past to present. Historical structures damaged for various reasons should be restored, repaired and strengthened. After these processes, the behavior of historical structures affected by environmental and time-dependent effects should be followed. For this purpose, current structural behavior of historical structures should be determined. Methods based on the dynamic characteristics of structure are very effective in the evaluation of structural behavior. In this study, dynamic characteristics of Tabakhane and Haci Kasim Muhittin Mosque Minarets in Trabzon province with different environmental conditions and different time intervals were experimentally obtained and compared. Experimental measurements of these minarets were carried out under environmental vibrations with Civil Engineering Vibration System (CEVS), which was developed by our research team, which can receive wired and wireless data. In Tabakhane Mosque Minaret, two measurements taken at different times before restoration and two measurements taken at different times after restoration were evaluated and compared each other. Measurement results of Haci Kasim Muhittin Cami Minaret before and after restoration and two measurements results taken at different times long after restoration were evaluated. The measurement data were analyzed separately in Civil Engineering Vibration Analysis (CEVA) program developed by our research team and in ARTEMIS program. In addition, dynamic characteristics obtained as a result of signal processing for both minarets were compared with previous studies. The reasons for differences in these values were examined depending on environmental condition and time.

Sancar, Canan; Akbaş, Yusuf Ekrem
This study tested whether there was a relationship between migration, unemployment, and urbanization based on the Harris-Todaro model in 12 regions of Turkey, which were formed according to NUTS-1 classification, in the period between 2008 and 2019. For this purpose, panel data methods that consider cross-section dependency were used in the study. As a result of the analysis, it was concluded that the Harris-Todaro model was valid in TR1, TR2, TR3, TR4, TR5, and TR6 regions. In TR7, TR8, TR9, TRA, TRB, and TRC regions, it was found that the Harris-Todaro model was not valid.

Araz, Onur
The dynamic responses of the buildings and the optimum parameters of tuned mass damper inerter (TMDI) may change significantly when soil-structure interaction (SSI) is considered. Thus, it is necessary to consider the effect of the SSI in the optimization of TMDI. The study aims at proposing a methodology for optimization of TMDI parameters in reducing maximum structural responses of a high-rise building under earthquake considering the SSI effects. The equations of motion for time-domain analysis are derived for obtaining seismic-induced vibrations of a multi-story shear building with TMDI when the SSI is considered. An improved particle swarm optimization (IPSO) is used to obtain the optimum parameters. The aim of the optimization is to reduce the amplitude of the acceleration transfer function (ATF). The effectiveness of the optimally designed TMDI is assessed for twelve earthquake records with different frequency contents. The effect of the different mass ratios (µ), inertance ratios (β) and support conditions on control performance of the TMDI are investigated in detail. Numerical results proved that the SSI effect and the inertance ratio have a significant impact on the optimal design and effectiveness of the TMDI. From the seismic analysis results, it is seen that the controlled displacement response usually increases with the increase in the inertia ratio for both the fixed and flexible foundation, and a lower seismic response is obtained in the building controlled by TMD compared with the TMDI with different inertance ratios.

Akgol, Kadir; Gunay, Banihan; Aydin, Metin Mutlu
Vertical traffic-calming applications may possess certain disadvantages. For instance, drivers sometimes apply a harsh brake very late or they may even prefer to accelerate rather than slow down to by-pass the suspension's shock threshold level. This has negative consequences on both vehicular and pedestrian traffic. In this study, the effects of chicanes-one of the most common horizontal speed reduction applications-on driver behaviour were examined and certain design characteristics were evaluated in the traffic laboratory of Akdeniz University in Turkey. To complete the driving tests safely and in an economical fashion, they were performed in a driving simulator. The trajectory data of some 125 drivers were saved by the simulator software. To examine these data in detail, a new method was developed using VisualLisp programming. The trajectory data were then transferred to an ArcGIS analysis program and the driving test data on the virtual chicanes were evaluated according to position and speed data. Finally, the optimum chicane design characteristics and their efficiency were determined.

Coruh, Emine; Urak, Faruk; Bilgic, Abdulbaki; Yen, Steven T.
Factors at the family scale, for which dynamic decisions and proper investments need to be made at the national level in curbing greenhouse gas emissions, are extremely important for policymakers and investors. We provide information on the roles of how household demographic factors shape transportation patterns and spending in Turkey using the latest survey data collected by the Turkish Statistical Institute (TSI). Alternative sample selection models are estimated to accommodate censoring in expenditure, and the dependent single-hurdle model is found to be the preferred model as a result of model specification tests. Also, different specification tests conducted, including the error-independence test, resulted in rejection of the null hypothesis. Results suggest that the majority of the household economic and sociodemographic characteristics are important determinants of both the probability and level of transportation expenditure. Policy recommendations to curb carbon emissions and integrate environmentally friendly transport systems throughout the country are presented.

Photovoltaic Power Plants have a considerable share among solar energy conversion technologies toward environmentally sustainable and economically feasible electricity production. However, when a rural region's land surface formed by natural soil types is covered by a Photovoltaic Power Plant (PVPP)'s dark-colored solar modules in large numbers, an artificial albedo (reflectivity) change is expected on that surface. Because of the heat exchange between these modules and the air surrounding them due to albedo alteration, the region's natural weather conditions may experience Photovoltaic Heat Island Effect (PVHIE) as a result of external and time-dependent air temperature oscillations caused by the warming-cooling cycles of solar modules. To observe and analyze a possible PVHIE trend, it has been conducting a field study project since October 2017 for a PVPP near the Sekbandemirli rural region in the Kutahya city of Turkey. The weather data, including air temperature and wind (direction and speed) at every 10-minute and hourly intervals, are collected by the three weather monitoring stations installed at the specific locations inside and outside the PVPP field. The plant's hourly average power output and module temperature data can also be monitored. After conducting statistical, correlational, and graphical analyses, the results show some temporal PVHI formations at the PVPP field center daily and on a seasonal basis. The plant center's air temperature tends to be warmer (up to the 6°C difference) during daytimes and colder (up to the (-3)°C difference) during nighttimes.

Ünlü, Ramazan; Kiriş, Recep
Detecting damaged buildings after an earthquake as quickly as possible is important for emergency teams to reach these buildings and save the lives of many people. Today, damaged buildings after the earthquake are carried out by the survivors contacting the authorities or using some air vehicles such as helicopters. In this study, AI-based systems were tested to detect damaged or destroyed buildings by integrating into street camera systems after unexpected disasters. For this purpose, we have used VGG-16, VGG-19, and NASNet convolutional neural network models which are often used for image recognition problems in the literature to detect damaged buildings. In order to effectively implement these models, we have first segmented all the images with the K-means clustering algorithm. Thereafter, for the first phase of this study, segmented images labeled “damaged buildings” and “normal” were classified and the VGG-19 model was the most successful model with a 90% accuracy in the test set. Besides, as the second phase of the study, we have created a multiclass classification problem by labeling segmented images as “damaged buildings,” “less damaged buildings,” and “normal.” The same three architectures are used to achieve the most accurate classification results on the test set. VGG-19 and VGG-16, and NASNet have achieved considerable success in the test set with about 70%, 67%, and 62% accuracy, respectively.

Küçük Matcı, Dilek; Çömert, Resul; Avdan, Uğur
Urban areas of major cities in developing countries are expanding rapidly due to rapid population growth and industrialization. Determining the reasons for rapid urbanization and the amount of urban area that will be needed in the future is important for the planned growth of these cities. In this study, the LU/LC change of Eskisehir city center that has a rapid rate of urbanization and industrialization in Turkey between 1984 and 2020 was determined. Then, the area needed for urban and industrial areas in 2030 was investigated using the Cullullar Automata–Markov Chain (CA–MC) hybrid model simulation. Each year's LU/LC map was produced with over 80% kappa accuracies performing the pixel-based Random Forest (RF) algorithm for change analysis. In the change analysis made between 1984 and 2020, it was determined that there was a change of 117% in the urban area and 977% in the industrial area. The prediction was made for the validation of the CA–MC model from the period 2000–2010 to 2020. When compared with the 2020 LU/LC map, the model success was obtained as 0.84, 0.87, and 0.87 in the Kstandard, Klocation, and Kno Kappa metrics, respectively. By using the 2010–2020 periods in the estimation of 2030, it has been observed that the urban and industrial area will increase by 22.95%; therefore, there will be decreases in agriculture and other natural areas as in previous years.
- MakaleYalnız künye2022Effect of earthquake frequency content on seismic-induced vibration control of structures equipped with tuned mass damper
Araz, Onur; Cakir, Tufan; Ozturk, Kasif Furkan
The main goal of this paper is to investigate the influence of the earthquake frequency content on the optimization of tuned mass damper (TMD) for multi-story buildings. Earthquake frequency content is divided into three groups (i.e., low, intermediate and high frequency content) according to the ratio of peak ground acceleration to the peak ground velocities. Time-domain analyses are performed to obtain the dynamic responses of 10-story and 40-story shear buildings equipped with a TMD under twelve different earthquake records. Advanced firefly algorithm is used to obtain the optimum parameters of the TMD such as the frequency ratio and the damping ratio. The optimization criterion is selected as the minimization of the maximum top story displacement of the building with TMD. The optimum parameters of TMD designed by this paper and its control performance are compared with those of other previous works available in the literature. Compared to the other methods, the optimum TMD designed by this study especially performs better in reducing the maximum top story displacements. Furthermore, it is discussed why TMD is ineffective in reducing the maximum floor accelerations of 40-story building, and then the effect of different mass ratios and objective functions in reducing the maximum responses of both buildings under critical earthquake excitation is investigated in detail. The results also show that the frequency content of earthquake ground motions has a significant effect on the optimum parameters of TMD and its control performance.

Araz, Onur; Ozturk, Kasif Furkan; Cakir, Tufan
This paper deals with the optimization of the tuned mass damper (TMD) with different objective functions for high-rise building under earthquake motions considering soil–structure interaction (SSI). A study is conducted to search for the TMD that outperforms five objective functions (i.e., OF-1–OF-5) containing combinations of the structural responses and foundation responses. The main goal of the present study is to evaluate and compare the control performance of these five objective functions. The optimum parameters of TMD are obtained by particle swarm algorithm (PSA) to minimize the acceleration transfer function. To determine the dynamic response of a 40-story building under the influence of SSI, six different foundation soil conditions and eight different earthquake records are considered. The results show that the SSI effects on the dynamic response of the high-rise building resting on relatively soft soil types such as SD and SE are of critical importance. It is shown that the effectiveness of the optimum TMD designed by OF-1 is better than the others in suppressing the peak response values for all soil types. After OF-1, the best performances are obtained for OF-3 and OF-5 which yield approximately the same effectiveness. It is also found that different earthquake records, soil types and objective functions are very effective on the effectiveness of TMD.

Çavdar, Özlem
In this paper, the seismic behavior of the existing reinforced concrete tall building is investigated by using the linear and nonlinear dynamic methods. The selected existing reinforced concrete structure was designed according to Turkey Seismic Code-2007. The performance analysis according to the Turkey Building Earthquake Code-2019 is realized in a 41-story reinforced concrete shear wall-framed structure in Istanbul where active fault lines are located. For high-rise building, firstly, spectrum analysis according to mode superposition methods of linear computational methods used within the scope of strength-based design is performed. Turkey Building Earthquake Code-2019 advises a nonlinear deformation-based design approach to determine more accurately the behavior of high-rise building, as in the earthquake regulations of other developed countries. In addition, the nonlinear time history analyses of building were performed. At the end of the study, torsional irregularity is seen on the normal floors and intermediate floor; stiffness irregularity was found on second floors. In addition, it has been observed in some of the oblique columns of the building that load bearing capacities were exceeded due to creep, axial compressive loads and severe damages occurred. According to the Turkey Building Earthquake Code-2019, the high-rise reinforced concrete shear wall building is not expected to satisfy life safety performance levels under design earthquake.

2019 yılı sonunda Çin’de ortaya çıkan COVID-19 Pandemisi, 2020 yılının ilk aylarından itibaren Dünya genelinde birçok alanda kısıtlamalara ve düzen değişikliklerine neden olmuştur. Diğer tüm alanlarda olduğu gibi ulaştırma hizmetleri ve ulaşım karakteristiklerinde de bu pandemi nedeniyle büyük değişiklikler görülmüştür. Ülkemizde pandeminin görülmeye başlandığı tarihten itibaren pandeminin seyrine ve virüse yakalanan vatandaş sayısındaki artışa bağlı olarak bazı dönemlerde sokağa çıkma kısıtlamaları getirilmiştir. Bu kısıtlamalara bağlı olarak toplu taşıma sefer sıklıkları, şehir içi ve şehirlerarası toplu taşıma hizmetlerini kullanan yolcu sayıları, trafikteki araç sayısı vb. ulaşım ile ilgili birçok alanda değişiklikler görülmeye başlanmıştır. Bu çalışma kapsamında, pilot kent olarak seçilen Antalya şehir merkezinde yer alan ana arterler üzerinde pandemi etkisi nedeniyle trafikteki araç sayısında meydana gelen değişimler incelenmiştir. Elde edilen sonuçlar detaylı olarak irdelendiğinde, pandemi sırasında kısıtlama günlerinde araç sayısında önemli derecede azalmalar görülmüştür. Yine elde edilen sonuçlara göre, ülkemizde trafiğe çıkan araç sayısında artış meydana gelmesine rağmen, kısıtlama günleri dışındaki günlerde trafikteki araç sayısının pandemi öncesindeki sayıya yakın olduğu görülmüştür. Bu sonuç, pandemi nedeniyle sürücülerin toplu taşıma yerine bireysel araç kullanımına yöneldiklerini doğrulamaktadır.

Kırsal yerleşim yerlerinden kentsel yerleşim yerlerine doğru işgücü göçü gelişmekte olan ülkelerde kentleşmenin önemli bir parçasıdır. Harris-Todaro (1970) tarafından geliştirilen işgücü göçü modelinde, artan kentsel ücret kentsel sektörde beklenen ücreti yükseltir ve bu durum kırdan kente göçü teşvik eder. Ancak, kentsel sektörde yaratılan istihdam olanaklarından daha fazla göç akımı olması durumunda işgücünün bir bölümünün işsiz kalması kaçınılmaz olur. İşgücü akımının devam etmesi durumunda ise kentsel işsizlik artarak, Todaro paradoksu denilen durum oluşur. Bu çalışmada Malatya, Van, Gaziantep Şanlıurfa ve Mardin Düzey 2 bölgelerinin iç göç, işsizlik ile kentleşme arasındaki nedensellik ilişkileri Harris-Todaro modeli ve Todaro paradoksu çerçevesinde araştırılmıştır. Bu amaçla, değişkenler arasındaki nedensellik ilişkileri 2008-2020 dönemi verileriyle panel nedensellik testi ile analiz edilmiştir. Malatya, Van, Gaziantep Şanlıurfa ve Mardin Düzey 2 bölgeleri için elde edilen analiz bulguları işsizlik oranlarından net göç oranına doğru tek yönlü nedensellik ilişkisi olduğunu göstermiştir. Ayrıca, bu beş bölgenin genelinde net göç oranından kentleşme oranına doğru tek yönlü nedensellik ilişkisi tespit edilmiştir. Çalışmanın sonuçları, Malatya, Van, Gaziantep Şanlıurfa ve Mardin Düzey 2 bölgelerinde Harris-Todaro modelinin geçerli olmadığını ve Todaro paradoksunun geçerli olduğunu göstermiştir. Todaro paradoksunun geçerli olması, bu bölgelerin kentsel yerleşim birimlerinde istihdam fırsatlarında veya diğer yatırımlardaki hızlı artışların kent merkezlerine göçü teşvik ederek, bir süre sonra kentsel işsizliği arttırdığı anlamına gelmektedir. Malatya, Van, Gaziantep Şanlıurfa ve Mardin Düzey 2 bölgelerinin kırsal yerleşim birimlerinde istihdam olanaklarının artırılması hem bu bölgelerde işsizliğin azaltılması hem de kırsal gelirin artırılmasında etkili olabilir. Bu sayede kentsel yerleşim birimlerine doğru gerçekleşen göç akımlarının Türkiye’nin sosyo-ekonomik göstergeleri üzerindeki olumsuz sonuçları en aza indirilebilir.

Inan, Halil Ibrahim
In Turkey, in the areas of rural planning and land management, problems regarding data retrieval, data quality, implementation scenario and legal base (law or regulation) have long been experienced. In this study, in order to contribute to resolving such problems, a conceptual/semantic data model was designed which focuses on the definition of required data, determination of their basic qualities and also their relations. As the preparation step for the model development, interviews, and discussions with authorized people were carried out. In addition, for the definitions of the data in the model, the Land Parcel Identification System and Infrastructure for Spatial Information in the European Community (INSPIRE) are considered. For the model design, an object-oriented modelling method with the Unified Modelling Language (UML) notation was used. In the model, planning activities were focused on. It is envisaged that the model will guide work for the preparation of a technical regulation which may enable a standardized implementation throughout Turkey. It has also the potential to be an example for the implementation of laws related to spatial data both in Turkey and also worldwide.
