Investigation of Relative Story Shifts in Buildings with Projection Irregularities at Different Ratios

Abstract

There are 3 major fault lines in our country, which is exposed to thousands of earthquakes every year, namely the North Anatolian Fault Line, the East Anatolian Fault Line and the West Anatolian Fault Line. Therefore, earthquake effects are more important in terms of the structural behavior of the buildings built in our country. It is very important for building safety to design buildings as regularly as possible during the design phase. However, sometimes this is not possible for reasons such as architectural designs. In the study, 6 different models with the irregularity type of A3-Existence of Projections in the Plane and the symmetric reference model were analyzed according to mode coupling. The models analyzed in the study were modeled in three dimensions from the SAP2000 program. As a result of the analysis, the relative storey drift performances of the models under the effect of earthquakes were examined. Comparisons were made in line with the results obtained from the analyzes and the relative folds of the structures with A3 irregularity type were made. Comments have been made about the effect on the displacements.
