Abstract:The project is a particularly irregular structure which is a bias multi tower with weak connection on an enlarged base situation, and analysis was conducted on the overall model, the tower model, and layer model. Elastic time-history analysis, static elastic-plastic analysis and floor stress contrast analysis were conducted to carry out a comprehensive study on the seismic performance of the structure through a variety of software. By setting the multi-directional frame beams, the integrity of the large base was improved, and anti-collapse seismic measures was set targeting at the key weak components. The results show that the calculated parameters of the structure meet the requirements of the code, and the effective seismic measures improve the seismic performance of the structure, and the structure is safe and reliable.
Keywords:particularly irregular; enlarged base; bias multi tower; elastic time-history analysis; static elastic-plastic analysis
