Discussions on the Seismic Performance Assessment Through a Case Study of "Sosyal Konutlar" Buildings in Famagusta

ABSTRACT: This research is to assess the performance of "Sosyal Konutlar Buildings" in Famagusta against earthquakes by using nonlinear static analysis methods. The assessment methodology involves two stages. First, the building data should be prepared such as available drawings, material properties, condition of the structural members etc. At the second stage, the data is used to model the building via the appropriate software. At the first stage, it was observed that these buildings have corrosion problem especially in the columns. Therefore, this problem and its effect on performance of the buildings have been taken into account. The corrosion effect of reduction in steel area, reduction in concrete strength and slip have been considered for the ground floor columns and their effect on seismic performance has been determined. In this study corrosion level of the ground floor columns have been considered as 5%, 10%, 15% and 20%. Buildings have been modeled as a two dimensional frame model with three types of loads, uniform lateral loads, triangular lateral loads and the first mode lateral load pattern. Although, the Turkish Earthquake Code design response spectrum has been used, the nonlinear static procedures of FEMA356 and Eurocode8 has been used. Results were obtained for both codes are discussed and comparison between both codes were explained. Keywords: Earthquake, corrosion, nonlinear static analysis. ……………………………………………………………………………………………………………………………………………………………………………………………………………………
