Comparative Study of Static and Response Spectrum Methods for Seismic Analysis of Regular RC Buildings

Abstract:
Background and Objective: The main idea in this paper is to study the static and dynamic analysis methods and compare their results in order to determine the optimal conditions for application of each method. Materials and Methods: In this research, two structural models are created using the ETABS (V16.1.2) program for regular R.C buildings with typical plans, the first model with a total height of 75 m while the second model with a total height of 24 m. The buildings are analyzed using the static and dynamic methods under ASCE7-10 and IBC 2015 provisions. Results: The results show that shear forces obtained using the response spectrum analysis as a dynamic analysis in the X directions are less than those obtained using the equivalent static analysis by 35-60 and by 40-65% in the Y direction for the high-rise building, while for the low-rise building is less by 25% in X direction and 22% in Y direction. The results also show the bending moments in the X directions obtained using the response spectrum analysis are less than those obtained by using the equivalent static analysis by 45-75 and by 30-65% in the Y direction for high-rise building, while for the low-rise building is less by 22% in X direction and 20% in Y direction. Conclusion: The results of displacements in the X directions obtained using the response spectrum analysis are less than those obtained by using the equivalent static analysis by 70 and by 80% in the Y direction for the high-rise building, while for the low-rise building is less by 35% in X direction and 38% in Y direction.
