摘要

摘要: 在基于性能的抗震设计中,增量动力分析法(IDA)常被用于计算结构的动力反应、损伤性能及可能的经济损失。这种设计方法弥补了传统单一的、基于生命安全的抗震设计方法的缺陷,能够可靠地保证建筑结构的功能在地震的作用下不致丧失乃至不受影响。采用IDA法对生态复合墙结构进行了抗震性能分析,提出了生态复合墙结构抗震性态目标量化的确定方法,并通过IDA曲线分析,得到了结构的倒塌储备系数(CMR),评价了生态复合墙结构的抗震性能。通过工程实例分析表明:在8度大震作用下,生态复合墙结构倒塌的概率较小,约为7.5%,具有较好的抗震性能。

Abstract: This design method makes up the defects of traditional single seismic design method based on the lifesafety, and can reliably assure the functions of structure not lose and not affected in the earthquake．It is adopted IDAto analyze the anti-earthquake performance of ecological composite wall structure, and put forward the determinationmethod of quantitative seimic performance objective of ecological composite wall structure, and then gets the thecollapsed reservation coefficient of structure through the analysis of IDA curve, and finally evaluates seismicperformance of ecological composite wall structure．The analysis of engineering example shows that under 8 degreeearthquake ( fortification intensity of this region), the collapse probability of ecological composite wall structure islow, about 7. 5 per cent, so its seismic performance is good．
