大开间小型混凝土砌块10层模型房屋抗震性能试验研究(II)
|
摘要
与粘土砖相比,混凝土砌块有诸多优点。但由于缺乏抗震经验,而且研究工作也不充分,所以规范对这类结构的规定一般偏于保守。本文通过1/4比例的10层大开间混凝土砌块模型结构的地震模拟试验,研究了砌块结构屈服机制,为结构设计及规范的修订提供了参考数据。
Compared with the common clay brick,the concrete hollow block has many advantages. But owing to lack of seismic experience and insufficiency of research,in design codes the regulations relevant to the conerete block structures were very conservative. In this paper the shaking table test results of a 1/4 scale 10 storied concrete hollow block model building are presented and the yielding mechanism is discussed in detail.
