摘要

本文分别对一榀框支短肢剪力墙斜柱式转换框架及一榀相同尺寸的梁式转换
框架两个试件进行了竖向荷载和水平低周反复荷载共同作用下的拟静力试验。观
察并记录了试件的开裂、屈服以及裂缝发展过程,测定了结构的变形及钢筋的应
变,详细描述了两个试件的整个破坏过程和钢筋应变发展规律,总结了两类转换
结构的基本受力特点。同时,根据试验数据对比分析了两试件的延性、耗能、强
度及刚度退化等规律,如实评价了两种试验模型的抗震性能,提出了斜柱式转换
结构的抗震设计思路。
本文研究结果表明,斜柱式转换结构受力特点类似于一个简单桁架,具有如
下特点:①传力直接、明确,传力路径清楚,构造较简单;②可有效的减小转换
梁的尺寸,充分利用层高,较易满足建筑功能要求;③转换层侧向刚度较大,不
易使转换层形成结构薄弱层;④与梁式转换结构相比,更易实现“强柱弱梁,强
剪弱弯,更强节点”的抗震设计原则;⑤只要设计合理,斜柱式转换结构可以获
得较好的抗震性能,是一种值得推广的新型转换结构。

ABSTRACT

This thesis carries out the pseudo static test, which are subjected to vertical loads
and horizontal cyclic loads, respectively on two specimens, including the framed
short-leg shear wall inclined column-shaped transfer plane framework and the same
dimension beam-shaped transfer structure frame. Then, observe and record the cracking
load, yield load and the development of cracks, measure the structure distortion and
strain of steel bars, describe amply the two specimens’ whole devastation process and
the strain of steel bars development regulation and finally sum up the two kinds of
transfer structures’ basic behavior characters. At the same time, contrast and analyze the
ductility, energy dissipation capability, and intensity & stiffness attenuation of the two
specimens, according to the experiment data. Appraise the two models’ seismic
behavior and bring forward the aseismatic design ideas of the inclined column-shaped
transfer structure.
The study results indicate that the mechanical behaviors characters of the inclined
column-shaped transfer structure are similar to that of a simple truss, including: ①The
load transfer is direct, specific, the transfer route is clear and the structure is simple. ②
It can reduce the beam dimension effectively, make full use of the story height, and is
easy to satisfy the architecture func
