无锡地铁控制中心为筒体严重偏置的框架-核心筒超高层结构,为充分了解筒体偏置对结构抗震性能的影响,本文对无锡地铁控制中心进行了弹性时程和静力非线性分析,对薄弱楼层采取相应的加强措施,并得到了性能点处的层剪力、层间位移角曲线和塑性铰分布。计算结果表明:该结构符合“强柱弱梁”的原则,能满足大震不倒的设防要求,其抗震设计理念对类似建筑具有较高的参考价值。
無錫地鐵控製中心為筒體嚴重偏置的框架-覈心筒超高層結構,為充分瞭解筒體偏置對結構抗震性能的影響,本文對無錫地鐵控製中心進行瞭彈性時程和靜力非線性分析,對薄弱樓層採取相應的加彊措施,併得到瞭性能點處的層剪力、層間位移角麯線和塑性鉸分佈。計算結果錶明:該結構符閤“彊柱弱樑”的原則,能滿足大震不倒的設防要求,其抗震設計理唸對類似建築具有較高的參攷價值。

Wuxi Subway control center is the frame-core tube high-rise structure.The core tube of the control center is se-riously biased.For the full understanding of the effects of cylinder body bias on structural seismic performance,the elastic time history and the nonlinear static analysis of Wuxi Subway control center are carried out in this paper.Corresponding measures are taken to strengthen the weak floor.The diagrams of storey shear,storey drift angle and the distribution of plastic hinges at performance point are obtained.The results show that the behavior of the structure accords with the princi-ple of “strong-column-weak-beam”,and it will not collapse under strong earthquake.The aseismatic design concept of this building has a good reference value for similar projects.
