Article Citation - WoS: 37Citation - Scopus: 39Re-Mapping Urban Vitality Through Jane Jacobs' Criteria: The Case of Kayseri, Turkey(Elsevier Sci Ltd, 2022-03) Pakoz, Muhammed Ziya; Yaratgan, Dilara; Sahin, AydanThere has been a growing debate in recent decades about the view of city and urban theory. The scope of this discussion has expanded with many different claims about the variable structure of the city and urban society, the boundaries of the urban scale, the nature of the city and urban problems. Jane Jacobs, one of the focal points of these discussions, has offered a different perspective with the approach of urbanism and the principles shaping the city's reconstruction: More important than how cities look is how they work. Therefore, human interactions which create a vibrant environment in cities should be considered to understand the dynamics of cities. Located in the central part of Turkey, the city of Kayseri is a rapidly growing industrial city with approximately 1.4 million population. Despite the fact that the city has a long history, the traditional urban pattern has been largely destroyed via planning decisions and the vast majority of the housing stock in the city has been renewed in the last 40-50 years. This paper examines the city of Kayseri using Jane Jacobs' criteria for what makes a city livable and vibrant. We re-mapped 87 neighborhoods of the city that constitute a continuous urban macroform by using the Kernel Density tool with ArcGIS software, evaluated the "urban vitality" of each neighborhood, and compared outputs with our observations to understand the relevance of Jacobs' views in different contexts. The main findings of the study reveal that not only historical and commercial centers within the city but also several transformed and newly built areas have high urban character values according to Jacobs' criteria. However, the degree of vitality (high, moderate, low, or non-urban), which is measured, may differ from the urban vitality, which is observed by the "naked eyes" in some neighborhoods of the city.Conference Object Evaluation of the Performance of Geotextiles Using Finite Element Analysis in the Settlement Results: A Case Study in Kayseri, Turkey(Korean Geosynthetics Society, 2018) Yalçın, Hakan; Akin, Muge K.; Çabalar, Ali FiratGeotextiles are successfully designated for the reinforcement of soils to solve certain settlement as well as bearing capacity problems in difficult ground conditions. Furthermore, geotextiles are used for the stability of man-made slopes. In this study, the performance of geotextiles for soil improvement is evaluated by considering various geotextile types that have different axial stiffness values. The stiffness values are compared using a finite element method (FEM) based software PLAXIS 2D. As case study, Kayseri Organized Industrial Site in Turkey was chosen for the comparison of these geotextiles for a specific soil profile during analyses. Besides, the FEM based approach is also considered for the settlement, axial force and the effective stress changes during the application of geotextiles. The selected geotextiles are also correlated using scanning electron microscope (SEM) analyses. The results indicated that the axial stiffness (EA) can be considered with the effect on the possible soil settlement and axial force values. The settlement values reduced with increase in stiffness of reinforcement. © 2021 Elsevier B.V., All rights reserved.
