多层大开间少内纵墙住宅结构模型试验研究

Model Test of a Six-Story RC-Masonry Mixed Structure with Fewer Internal Longitudinal Walls under ReversedCyclic Loading

多层大开间少内纵墙灵活住宅结构体系是在外砖内模大模板体系的基础上，扩大开间，减少内纵墙，使开间和进深两个方向都有灵活性，实现建筑平面的多样化。为了研究这种体系纵向的抗震性能，在清华大学结构研究室完成了一座四分之一缩尺模型静力反复加载试验，研究了这种结构的受力机制、破坏特点及抗震性能，并提出了有关的设计意见和建议。

A structural system called multi-story RC-masonry mixed structure used for residential building with fewer internal longitudinal walls possesses many advantages,especially its flexibility in architectural layout of the building. In order to study the seismic performance of such kind of structures, a 1/4 scale six-storey model has been tested under reversed cyclic loading. Results of the experiment are presented in this paper with seismic behavior of such structure discussed. Finally, some suggestions for design are proposed.
