Comparison of Equivalent Static Analysis and Mode Combination Method for Concrete Buildings According to Turkish Standard

Abstract

This study aims to define the impact of analysis methods that are used to design buildings and offers their analysis. As a matter of fact, there are several methods for fundamental analysis of buildings and other civil engineering structures under seismic situations. Both can be differentiated in the shape of the seismic involvement and in the structure idealization. There are two measures to identify seismic design forces: one is the equivalent static force, and the other is dynamic analysis which can be in many forms. One of these forms is the superposition mode. This research aims to study the impact of these methods in the analysis of a six story concrete building; both results, obtained from the static and dynamic, will be ultimately compared. The results show that in a MDOF system, such as with six floors or more, the dynamic analysis will lead to displacements and smaller forces compared with the static process.
