Abstract

In practical engineering, the use of double-tower structures with large chassis is becoming increasingly widespread due to their novel shapes and diversified functions. However, the previous earthquake damage shows that complex structures are more prone to damage, and their irregularity aggravates the response to earthquake. In this paper, SAP2000 software is used to establish a model for static elastic-plastic (Pushover) analysis of the large chassis double-tower structure, to investigate the location of the performance points and the distribution of plastic hinges under multiple encounters and rare earthquakes. The results show that under the action of earthquake, when the target displacement is reached, no plastic hinges appear in any of members, which meets the design requirements; the plastic hinge first appears in the beam, and then appears in the column, mainly showing the B state plastic hinges, and the structure has good seismic performance, meeting the seismic design requirements of “strong column and weak beam”.
