加强层的设置对超高层框筒结构水平位移的影响

分析了加强层对控制结构水平位移的力学过程，建立了8个带有水平加强层的框架-核心筒高层结构模型（本文的基本模型是以西安市某大厦为背景，主体结构37层，塔楼2层，地下2层；结构总高度158．80m。下部采用桩筏基础。在这个模型基础上稍作改动，将其中的第4层、17层、37层做成加强层，产生7个新模型）。并用有限元软件分析了水平地震荷载作用下结构的顶点位移和最大层间位移，并根据理论分析和一系列数值比较，得出了加强层的设置数量和最优位置的结论。另外提出了对梁式加强层提高结构抗侧刚度的有效手段。研究结果可供实际工程参考。

Strengthened storey influence on horizontal displacement of super high-rise frame-core wall structure

The author analyzed mechanism theory that strengthened storey controls horizontal displacement,established 8 high- rise frame-core wall structure models(The one of mansions in XI'AN was chosen as elementary model,which main structure was 37 floors except that tower was 2 floors and basement was 2 floors.Its total structure height was 158.80m.Pile-raft foundation was used in underground structure.The model would be changed little in 4~(th),17~(th) and 37~(th) floor in which the strengthened storey would be s...
