(汉嘉设计集团股份有限公司, 杭州 310005)[摘要]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。[关键词]搭接柱; 转换结构; 应力分布中图分类号:TU318.2 文献标识码:A 文章编号:1002-848X(2014)05-0071-03Design research on transfer structure with the lapping columnsWang Shicun(Hanjia Design Group Co., Ltd., Hangzhou 310005, China)Abstract: 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.Keywords: lapping column; transfer structure; stress distribution作者简介:王世村,博士,高级工程师,一级注册结构工程师,一级注册建筑师,Email: davenport1979@163.com。参考文献[1]徐培福,傅学怡,王翠坤,等.复杂高层建筑结构设计[M].北京:中国建筑工业出版社,2005.[2]傅学怡.空间结构理念在高层建筑中的应用与发展[J].空间结构,2009, 15(3):85-96.[3]李亚娥,李洋,于法桥,等.搭接柱转换层结构设计时相关问题探讨[J].甘肃科学学报,2009,21(4):72-76.[4]李亚娥,王邓峮,于法桥,等.搭接柱转换层结构的静力有限元分析[J].甘肃科学学报,2010,22(1):134-137.
