Study on Model Pushover Analysis of Steel Grid Box-like Structure

In this paper,based on the research object of a 12-storey residential building,the steel grid box-like structure model and the ordinary steel frame structure model were respectively established.Through the structural seismic design for frequent earthquake intensities,the MPA method was used to calculate the target displacements of the two structures under rare earthquake intensities,with the lateral displacement stiffness,layer displacement,interlayer displacement angle and high-order vibration modes of the two systems comparatively analyzed.The results show that the seismic design index of the box-like structure meets the standard and is superior to the frame structure;the box-like structure has greater anti-seismic property in rare earthquakes than the frame structure,and its high-order vibration effect is less than that of the frame structure.
