Seismic Performance Analysis Of Concrete Structures

With the modern people’s living standard and the comprehensive development of the technology in the field of Architecture,more and more people are thinking about the quality of life and the safety of people.People are more and more high demand for the earthquake resistance of the daily residence.But the recent earthquake activity in China and abroad has become more and more frequent.Especially,the China’s Wenchuan earthquake, the people of our country caused great disaster.Therefore, how to increase the seismic stability of the structure is the most important problem to be considered in structural design.This article is through an example analysis of how to increase the seismic stability of the building structure.Factors affecting seismic stability include site selection, structural setting, structural form, and structural angle.The PKPM is used to model the seismic stability of frame structure and frame shear wall structure by SATWE finite element analysis.The main contents of this paper are as follows:First,Earthquake condition and frame structure and frame shear structure in modern world;Second, establish two kinds of different structure models through the PMCAD module of PKPM,, and the finite element analysis is carried out by SATWE;Third,the results of the two models are compared and analyzed, including the period of vibration, the maximum displacement of the floor and the displacement angle of the maximum layer, the seismic force and so on;Fourth,the prospect of the significance of the research.
