搭接柱转换结构设计研究

Design research on transfer structure with the lapping columns

对搭接柱转换结构的适用范围和受力特点进行了探讨。对搭接柱及其相邻构件进行了有限元分析,得出了搭接柱的应力分布、相关楼板的应力分布以及受拉梁、板中轴力的分担比例,并对施加预应力前后构件的应力分布变化进行了研究。对一幢局部采用搭接柱转换结构的建筑进行了整体计算,总结了一些设计的关键参数和构造措施。

The application scope and mechanical properties of the transfer structure with lapping columns were discussed. The stress distribution of the lapping columns and its adjoining floor slabs was analyzed by finite element program. The proportions of the force in the beam and floor slab were calculated too. The changes of stress distribution with and without prestress were researched. The total model of a building with lapping columns transfer structure was calculated, and some design parameters and details were obtained.
