Seismic Performance Analysis Of H-type Irregular Frame Structure

With the rapid development of urban construction,the use of buildings tend to diversify,a variety of modeling of the building a large number of irregular high-rise buildings have emerged.In the irregular structure,it is obviously important to analyze the seismic performance of the structure due to the complexity of the structural arrangement and the seriousness of the consequences of the earthquake disaster.In this paper,the seismic behavior of the icarried out,followed by the seismic response spectrum analysis and the linear dynamic time history analysis of the structure under the one-way and two-way earthquakes.Finally,the structure is analyzed by static push-off.Mainly from the following aspects of the structure of the study:1.For the plane irregular structure model,the dynamic parameters of the structure are obtained by modal analysis method,and then the vibration modes,the vibration period,the quality participation coefficient and the deformation characteristics of each model are compared and analyzed.The response spectra of the two groups are analyzed by the uniaxial seismic response.The displacement of the structure is analyzed,and the inter-layer displacement angle is calculated to judge the seismic performance of the structure.Then,the structural response of the two groups under the two-way earthquake To analyze.According to the analysis of the model in the one-way and two-way seismic action,it can be seen that the reasonable setting of the shear wall can improve the seismic performance of the structure.3.The three kinds of seismic waves are used to analyze the dynamic time history of model two and model three,and the acceleration response and displacement response of the structure are obtained to evaluate the response of each structure under earthquake action.The static buckling analysis of the model is carried out,and the seismic performance of the structure is further evaluated by analyzing the structural performance points and studying the development and distribution of plastic hinges.
