［摘要］结合无锡蓝庭国际在层8转换的部分框支剪力墙结构设计，分析了带高位转换结构的竖向规则性，发现在转换层处，框支柱、剪力墙存在剪力突变，转换层下一层与转换层刚度比小于50%。结合该工程设防类别及规则性，针对结构和关键构件提出不同的抗震性能设计目标。对转换层及其上下层楼板在各级地震作用下的楼板应力进行了分析，并给出了便于工程应用的转换层楼板配筋计算方法。合理布置结构，避免结构刚度柔软层为承载力薄弱层。弹塑性分析表明，经过合理布置后的结构无明显薄弱层，具有良好的屈服机制。

Abstract: Based on structural design on a frame-supported shear wall structure of Wuxi Lanting Guoji with transfer story at the 8th floor, the vertical regularity of high transfer structure was analyzed. The results show that shear force of the column which supports transfer beam and shear wall mutates near the transfer story; the stiffness ratio of transfer story and the story below was less than 50%. Based on the seismic fortification and regularity of the project, aiming at structure and key elements, different structural seismic performances were presented. The slab stress of transfer story and the story below (above) under different seismic load was analyzed. A calculation method for reinforcement of transfer story slab was proved. Soft story can be avoided to be weak story by reasonable layout of the structure. Results of elasto-plastic analysis indicate that the structure has no obvious weak story, and it has an excellent yield mechanism.

Keywords: high transfer story; storey height of transfer story; vertically irregular; slab design method of transfer story
