某复杂多塔连体超限高层结构设计

Strucutral design of a complex overrun high-rise building with multi-towers and connecting bodies

该项目为复杂多塔连体超限高层建筑,结构中存在多塔、楼板不连续、连体及局部穿层柱等不规则类型。针对工程特点,探讨了结构体系及布置、结构超限等方面情况。结合超限情况,给出了不同的超限处理措施。同时给出多遇地震作用下反应谱、弹性时程及罕遇地震作用下静力弹塑性等相关分析结果,结果表明结构各项指标均比较理想,整体设计满足设定的性能目标要求。

The project is a complex overrun high-rise building with multi-tower and connecting bodies.The building includes irrerular structures such as multi towers,discontinuous floors,connecting bodies and local skip-floor columns.According to the engineering characteristics,the structural system and structural ultra limit measures were discussed.The results of response spectrum analysis and elastic time history analysis under frequent earthquake and push-over analysis under rare earthquake were provided.It shows that the structural performance is relatively good and the overall design meets the set performance requirements.
