框支不满跨剪力墙的传力机理（Ⅰ）──有限元分析

LOAD-TRANSFER MECHANISM OF RC FRAMSO-SHEAR WALL WITH WALL WIDTH LESS THAN SPAN LENGTH (I)-FINITE ELEMENT ANALYSIS

当前在高层建筑中常遇到框支不满跨剪力培这种结构布置形式。本文用弹性有限元法分析了剪力墙不满跨布置时的内力分布特点，并与满跨情况作对比，发现后者的拉力拱式传力模式在不满跨时已不能形成。通过分析各种宽度剪力墙情况获得此种结构的传力机理，为结构设计提供参考依据。

A special form of framed-shear wall is encountered in high- risebuildings, i. e., a framed shear wall with the wall width less than the spanlength.In this paper the finite element method is used to analyze the influenceof shear wall width on load transfer path in the structure. In comparisonwith the case of full-span shear wall,it is found that the tie-bar archmechanism can not be formed. A full understanding of the load transfermechanism for such structures is reached. This will provide a reference basefor design of the structures.
