某超限高层框筒结构弹塑性动力时程分析

摘要

Dynamic elastic-plastic analyses are carried out for a tall frame-corewall structure by the commercial FE program MIDAS BUILDING. The structural dynamic response and member plastic developing process are investigated under practical earthquake effects, and seismic perform- ance of structure is meanwhile evaluated. Proposals are also put forward for improvement of engineering design.%应用MIDAS BUILDING结构软件对一个高层框筒结构进行了罕遇地震下的动力弹塑性分析,给出了结构在实际地震作用下的动力响应及各部位、构件的塑性发展情况,对结构的抗震性能做出评价,并对工程设计提出改进建议。
