Earthquake Response Analysis Of High Steel-concrete Structure Based On Random Vibration

The earthquakes are common in China. In the research of these large structure of seismic, the fierce space effect of the earthquakes should also be taken into consideration. To generalize rich achievements of this technical discipline in the application of the engineering. The paper analyses steel-concrete hybrid structure in the action of random vibration in aspects of the calculating method of structural response and the characteristic of earthquake response. The main research contents are as follows:1. Collecting materials,calculating correlation parameters, and drawing accelerating curves of white noise model.The pseudo excitation method for random vibration analysis are studied, which can be used for analysis of random earthquake response of steel and concrete mixed structure,and verify its correctness in theory.2.Then to determine the acceleration input model. With random vibration pseudo-excitation method to calculate relative stormy displacement of the multistory framework structure. And the result compared with which accumulated by Ansys of SAP2000, proves the accuracy of the Power spectral analysis.3.To research the law of random response for multistory framework structure in the action of random seismic with SAP2000,has got some beneficial conclusion about multistory framework structure in the action of the earthquake.
