| 摘 要： | 使用PMCAD软件,通过某模型工程对细腰复杂截面高层建筑结构的抗震性能进行了分析.结果显示细腰的程度越大,结构整体抗震性能越差.认为细腰平面做为组合平面的一种,在所列三项及三项以上不规则高层建筑做为其中一项进行控制,而不单独做为一项进行控制较为合理.

| Abstract: | By using PMCAD and SATWE softwares from China Academy of Building Research, taking a model building as the example, the analysis of seismic performance including vibration characteristics and components internal force status for thin-waist plane tall building is maken with the retraction of section plane. The result shows that the thiner the waist is, the worse the seismic performance is. It is considered that the thin-waist plane should be treated as one of three or more of extra-limit determinings, but not as single one. |
