Abstract:In order to accurately reveal the collapse mechanism of weak parts of slab-column shear wall structure under earthquake actions, explicit computing platform of ABAQUS software was used for secondary development. The calculation program was suitable for simulating the collapse of the building structure subject to the earthquake. First, the credibility of the results of the development program was verified from the component and overall levels. Secondly, combined with the engineering example of a slab-column shear wall structure, the elasto-plastic time-history analysis and the numerical simulation of the collapse process were conducted under the fortification, rare and super rare earthquakes. Through the contrast analysis, the results show that the precise elastic-plastic time history analysis is obviously superior to the equivalent elastic algorithm method, and setting of inner beam is helpful to improve the anti-collapse ability of the structure. A method of improving the collapse resistance of the structure by increasing the thickness of the bottom floor and the reinforcement ratio of the main wall was put forward. This method can not only significantly improve the seismic performance of the structure, but also ensure the economy to the greatest extent.
Keywords:slab-column shear wall structure; ABAQUS software; collapse analysis; weak part; seismic performance
