Research on Applications of Earthquake Response Spectrum in Engineering Designs

Earthquake-proof buildings are earthquake disaster mitigation priority work. Earthquake building structure may be determined, according to the design response spectrum method for determining been widely used in seismic design of buildings structures. In this paper, the structure should be designed to avoid damage in the earthquake collapsed, but the study of structural collapse behavior conducive to a better understanding of the mechanism of structural collapse and find effective anti-collapse methods. This paper was developed to simulate the complex structure collapsed procedures, through the numerical results were compared with the test, indicating that the numerical model can simulate the structural members of a variety of extreme nonlinear behavior. The structure is replaced by an equivalent single degree of freedom system corresponding to each mode and each equivalent displacement is determined using the proposed method. Thus, the seismic safety evaluation plays an important role. In recent years, with the accumulation of mature safety evaluation theory and engineering experience, the safety assessment has made great progress.
