某地铁上盖物业超限高层弹塑性地震反应分析
Analysis of elasto-plastic seismic response of an ultra-limit over-track building
【摘要】 选取5组天然波和2组人工波,采用弹塑性时程分析方法对某地铁上盖物业超限高层进行分析,研究整体结构在强震作用下的动力响应和地震损伤破坏情况并在此基础上对整个结构及相关构件抗震性能进行评估。分析结果表明:在罕遇地震作用下,该结构具有合理的屈服耗能机制,满足预先设定的抗震性能目标。
【Abstract】 Dynamic elasto-plastic time-history analysis method was conducted to investigate an ultra-limit over-track building and five natural waves together with two artifical waves were inducted to study the dynamic response of the structure and the degree of damage of structure members under rare earthquakes,meanwhile,the seismic performance evaluation of overall structure and corresponding comporents was made.The results show that this ultra-limit building structure has effective yielding mechanism under rare earthquakes and can fulfil the pre-set design goals of the seismic performance.
【Key words】 over-track building; ultra-limit tall-building; elasto-plastic time-history analysis; seismic performance;
