“…Seismic researches on historical structures have an important place in order to transfer the historical heritage to the next generations, nowadays. There are many studies in the literature about this topic (Hadzima-Nyarko et al, 2017;Erdil et al, 2018;Hadzima-Nyarko et al, 2016;Backer et al, 2018;Uğurlu et al, 2017;Özbek et al, 2017;Preciado et al, 2015: Işık et al, 2018Mutlu and Şahin, 2016). In all of these studies, seismic behaviors of different structures in different regions have been tried to be determined.…”

There are many historic buildings belongs to many civilizations in the Ahlat province. The fact that these structures survive for a very long time is directly related to the construction techniques of these structures. Emir Bayındır Bridge is one of the buildings that could stay solid. With this study, it is aimed to investigate the behavior of the bridge under earthquake effect. First of all, general information is given about the bridge. In this study, structural analyzes were carried out for the Ahlat Emir Bayındır Bridge after on-site inspections. Information about the damage that occurred over time in the bridge is given in this study. Observation based structural analysis form has been created for the bridge. A finite element model of the bridge was created with the help of on-site measurements. Analyzes were made for the created finite element model in different load cases. The obtained results were interpreted and recommendations were made.

In this study, the seismic response of the anchorage used for switchboard cabinets at a power plant was presented based on the results of an experiment and numerical simulations. In the experimental study, shaking table tests were performed to investigate the overall structural behavior of switchboard cabinets. The finite element modeling was conducted using the ABAQUS program, and in order to validate the proposed finite element model, the natural frequency, stress, and displacement were compared with the experimental results. A slight difference was found in the results due to the problem cup-like deformation at the anchorage of the bottom, but it showed reasonable agreement when considering the results for all behaviors. Using the proven model, nonlinear dynamic analysis was performed using three types of a period waves. The maximum stress on the anchorage occurred when a long-period wave was applied, and the horizontal maximum displacement of the cabinet was approximately 10 times greater than when an ultra-short-period wave was applied. It is expected that the flexibility of the cabinet stiffness resulted in more structural weakness, especially under a long-period wave, and that is recommended to focus on displacement rather than stress when establishing seismic design guidelines for switchboard cabinets.

Development of Seismic Vulnerability and Exposure Models—A Case Study of Croatia

et al. 2020

View full text Add to dashboard Cite

Assessing earthquake risk and building vulnerability requires an exposure model. These exposure models quantify the building stock in terms of structural characteristics, spatial location, and occupancy. The most significant exposure parameters are the structural characteristics of buildings, which must be uniformly covered by structural typologies. Structural typologies that take into account the regional specificities of design and construction provide more accurate and reliable exposure models. Despite the long history of earthquake engineering in the Republic of Croatia, the assessment of exposure and vulnerability of buildings is a rather new concept, hindered by the fact that no city in the Republic of Croatia has a database on the number, types, and characteristics of existing buildings. The article presents the creation of a building exposure model for the city of Osijek, points out the problems and concerns that the realization process brings, and details the practical solutions and strategies that have been used to achieve the set goals.
