摘要
庆化开元高科大厦是B级高度的复杂高层建筑结构 ,其建筑竖向上的结构转换层与建筑使用功能转换层不在同一层 ,且结构转换层上下两部分的轴网呈 45°相交 ,这给结构设计带来了较大的难度。重点介绍了转换层的选型、整体计算模型的处理 ,并提供了控制转换层上下层等效剪切刚度比、层间侧向刚度比的有效方法 ,很好地处理了建筑转换层、设备转换层、结构转换层之间的关系。
Qinghua kaiyuan high tech mansion is a complex high rise building with B grade height.Structural transfer story and that for facility are not in the same floor,and the axis nets of the two structural parts on and under the transfer story are intersectant in 45°angle,which make structural design more difficult.How to choose the transfer structure and dispose the total computation model is mainly discussed.In addition,the efficient methods for controlling the equivalent shear stiffness ratio between the upper and the lower one of the transfer story and the interlayer lateral stiffness ratio are also investigated,which well solves the setting of the architectural transfer story,the structural one and that for facility.
