搭接柱转换结构的试验研究与设计要点

Experimental Research and Main Points of Design Method on Lapping Column Transfer Structure

介绍了搭接柱转换结构的特点 ,通过 1∶5结构模型静力试验研究 ,分析了竖向荷载作用下搭接块、受拉楼盖、搭接块上下柱的裂缝开展情况、预应力施加效果、应力分布、破坏形态及承载能力等 。

The characteristic of transfer bracket is studied.A static 1/5 structural model test of transfer bracket was carried out in China Academy of Building Reasearch.The crack development,effect of prestress,distribution of stress,form of failure and carrying capacity of the model under vertical load action are studied.Some design suggestions for the transfer bracket,floor above the transfer bracket and columns connected to the transfer bracket are provided.
