Investigation of the effect of torsional irregularity on earthquake behaviour

Abstract

One of the major reasons for damage to the buildings during the earthquake is the vertical and plan irregularities in the buildings. Torsional irregularity is a type of irregularity that is included in many earthquake regulations in the world as irregularity. Knowing the factors affecting torsional irregularity by investigating the behavior of torsional irregular buildings is very important for avoiding this irregularity. In this study, the different number of story and the different located shear wall in plan were handled. Earthquake analyzes of these buildings were made separately for the three different earthquake analysis methods defined in Turkish Earthquake Code-2007 (TEC-2007). The variation of the torsional irregularity according to the number of story and the earthquake analysis method was investigated.
