摘要
重庆银行大厦属于平面不规则超限结构。本文对这种结构进行了弹性和弹塑性地震反应分析对比,并针对薄弱楼层做了专项分析。分析结果表明,结构各主要参数指标均能满足规范要求,设计方案合理可行。最后通过结合一系列的抗震构造措施,实现结构的抗震性能目标,保证结构的安全性。
The Chongqing Bank Building is an irregular plane super structure, the paper compares this structure＇s seismic response concerning elastic and elastic-plastic analysis, and conducts a special analysis for the weak floor. The results show that the main parameters of the structure can meet the target standard, that the design proves to be reasonable and feasible. The designing programm achieves all the objectives regarding structural seismic performances, ensures the safety of the structure by combining a series of seismic fortification measures.
