摘要
短肢剪力墙是近年来在我国兴起的一种新型抗侧力构件,它既保留了异形柱
结构不凸出墙面的优点,同时又克服了异形柱结构抗震性能不理想的缺点,而且
与普通剪力墙相比,又具有质量轻、开洞率大、延性更好等优点,因此短肢剪力
墙已在我国多、高层建筑中得到了广泛的应用。但是由于短肢剪力墙出现得较晚,
目前对它的研究工作还很少,主要的学术论文全部都是国内学者发表的,国外并
没有关于短肢剪力墙方面的论文发表。因此短肢剪力墙的设计和理论还没有形成
一套完整的体系,这给设计工作带来了一定的盲目性,很多设计人员在设计的工
作中不得不尽量避免使用这一结构形式,阻碍了短肢剪力墙结构的进一步推广。
本文在前人的研究基础之上,导出了短肢剪力墙墙肢轴压比限值的理论公
式,并通过模型试验,验证短肢剪力墙在施加了竖向荷载后的破坏形态和延性。
内容包括:
1. 导出了短肢剪力墙墙肢轴压比的计算公式,包括一字形墙肢截面和T形墙肢
截面并给出了各抗震等级下的轴压比的限值;
2. 制作了一榀4层对称双肢短肢剪力墙构件,并进行了低周反复水平荷载的试
验,研究了加有竖向荷载的短肢剪力墙的滞回特性、破坏形态。
3. 分析了试验结果提出了短肢剪力墙是一种具有良好的抗震性能的结构形
式。

Abstract
Short pier sheer wall is a new ponent to resistant lateral load acted on
buildings, which springing up in China in the recent years. Some excellences of
irregular cross-section column frame such as no extrusive columns appeared in the
wall or at the corner of the room are reserved. On the other hand, some shortages of
them such as the bad performances of seismic resistance are e by employing
the shear wall with short piers instead of the irregular cross-section column frame in
the building with ordinary shear wall,short pier sheer
wall is more lighter, more higher opening rate and more better ductility. For those
reasons the short pier shear walls are widely used in the middle or high-rise buildings.
However, there are plete theories available to guide the design of this type of
shear walls due to the lack of research on it. Published research papers mainly came
from domestic, there is no paper can be posed by oversea researchers. So
many structure designer avoid to use this new ponent, and this is an obstacle
for short pier sheer wall to be more widely used.
Based on previous researches,this dissertation is going to do some further
research on the aseismic performance of short pier sheer wall. The mec
