框支不满跨剪力墙的传力机理（Ⅱ）──试验研究

LOAD-TRANSFER MECHANISM OF RC FRAMED-SHEAR WALL WITH WALL WIDTH LESS THAN SPAN LENGTH (Ⅱ)-EXPERIMENTAL STUDIES

本文针对高层建筑中框支不满跨剪力培这种结构布置形式，在理论分析的基础上进行了试验研究。按１／４比例设计了剪力墙宽度为满跨、２／３跨、１／２跨等三个试件，施加竖向荷载进行破坏试验，观察试件的传力机理，与理论分析结果互相印证。通过试验初步探明结构的破坏形态与剪力墙宽度的关系。

This paper deals with experimental studies of a special form offramed-shear wall, i. e., a framed shear wall with the wall width less than thespan length. Three specimens with 1/4 scale are designed. The wall widths are l,2/3 and 1/4 of the span length, respectively, the specimens are subjected to vertical loadings. The load transfer mechanism observed in the tests are comparedwith theoretical results. A full understanding of the load transfer mechanismsand the failure modes related with the wall width are reached.
