某广场式大底盘高层商住楼工程,将设计中常采用的大底盘框支转换多塔楼复杂高层结构改变为无转换层、非大底盘的独立剪力墙+多层裙房纯框架结构,从而避开了规范规定的复杂高层建筑结构的出现。针对主塔高宽比超限采取了特殊加强措施和严格的位移控制。重点介绍了结构设计的全过程,包括结构方案的考虑、基础方案的比较、抗震计算分析以及抗震构造措施。可为类似工程结构设计提供参考。
A square plaza high-rise commercial and residential buildings, the design will often be used in large chassis frame conversion multi-tower complex high-rise structure without conversion layer, non-large chassis independent shear wall + multi-layer podium pure frame structure, thus Avoid the appearance of complex high-rise building structures as required by the code. For the main tower aspect ratio over the special measures taken to strengthen and strict displacement control. The whole process of structural design is emphasized, including the consideration of structural schemes, the comparison of basic schemes, the calculation and analysis of seismic resistance and the measures of anti-seismic structure. For similar engineering design provides a reference.
