Abstract

In recent years, nonlinear calculation methods can be easily carried out by means of developing computer technologies. In this way, comparisons of the nonlinear methods have started to increase rapidly and more studies are carried out on regular and irregular buildings. However, it is most important to compare consistency of the methods on buildings. In this study, most common nonlinear static (pushover) and nonlinear dynamic analysis (time history analysis) methods were compared on an asymmetric planned reinforced concrete (R/C) building. Building having horizontal and vertical irregularities was 5-story. Analyses were carried out by using SAP2000 program. The results are discussed in terms of base shear, lateral displacements and top displacement ratios.

Highlights

  • It is possible to use linear or nonlinear methods in seismic analyses of structures

  • The results of the building are presented in terms of base reaction, lateral displacement, top displacement ratio and interstory drifts for different level of seismic intensities

  • Comparison of the difference between nonlinear static pushover (NSP) and time history (TH) analysis in terms of interstory drifts, the results show that NSP values generally follow TH values

Summary

Introduction

It is possible to use linear or nonlinear methods in seismic analyses of structures. Linear analysis uses the methods of the elastic solution. It is need to include inelastic behavior of structural elements for more realistic results. Nonlinear time history (TH) analysis is the represents the most actual behavior of the structure. Past studies shows that nonlinear pushover (NSP) analysis is suitable alternative to TH by correct selection of parameters and assumptions. ATC 40 [6], FEMA 273 [7], FEMA 356 [8] and FEMA 440 [9] procedures were introduced In parallel with these procedures, Turkish Seismic Code (TSC-2007) came into effect in 2007 [10]. Bhatt and Bento [11] presented on assessment of two existing five and eight story plan asymmetric buildings in Turkey.
