摘要

利用MIDAS/Building程序对某双塔连体超限高层建筑结构进行动力弹塑性分析,结合该结构特点从不同角度分别研究结构在实际地震作用下将出现的破坏模式、塑性发展特点等。结果表明,罕遇地震作用下结构最大层间位移角为1/250,满足有关规范规定的限值要求,结构框架柱及连接体未出现破坏,筒体剪力墙底部加强区出现剪切型损伤。整个结构构件塑性铰出现顺序和分布较为合理,满足"大震不倒"的设防要求。
Elastic-plastic dynamic analysis was performed on the double tower connected structure of a building by MIDAS/Building software under the rare earthquake load. Failure modes and plastic zone development were researched according to the feature of the structure. Results show that under the rare earthquakes, the maximum inter-story drifts are less than that of the requirements of the Chinese seismic design code. There is no damage in the columns and connected structure . A few shear walls of the tube are damaged at the reinforcing area of bottom. The order and distribution of damage in the components of the tubes are reasonable. It can fulfill the seismic fortification criterion of "no collapse under rare earthquake".
