建筑结构层间搭接柱转换结构设计

Design of interlayer lapping column transfer structure in building structure

基于某实际项目对层间搭接柱转换结构进行设计,采用通用有限元程序SAP2000分析了层间搭接柱转换结构在竖向荷载及多遇地震作用下的力学性能。结果表明：层间搭接柱可以良好地发挥其空间效应,更合理、经济地解决由于建筑立面收进而引起的柱错位问题,并提出了一系列基于层间搭接柱的构造措施以及层间搭接柱分析设计的关键控制要素。

Based on a practical project, the transfer structure of interlayer lapping columns was designed, and the mechanical properties of interlayer lapping columns under vertical load and frequently occurred earthquake were analyzed by general finite element program SAP2000. The results show that the space effect of interlayer lapping columns can be well exerted and the problem of column misalignment caused by the construction facade can be solved more reasonable and economical. Furthermore, a series of structural measures and the key control factors of design about interlayer lapping columns were proposed.
