摘要
轻钢轻混凝土墙体局压研究可以有效拓展轻钢轻混凝土结构的适用范围,实现大开间、退台、跃层等诸多的建筑风格。本文通过轻钢轻混凝土墙体中心局压和边角局压试验,分析了局压破坏形态及局压荷载下墙体轻钢与轻混凝土应力变化规律,结果表明局压荷载由局压点轻钢立柱和轻混凝土共同承担,二者协同工作,且整个承载受力过程中轻钢立柱的荷载分担比例基本不变,基于此,提出了局压承载力计算方法。
The research on the local compression of lightweight steel and lightweight concrete wall can effectively expand the scope of application of lightweight steel and lightweight concrete structures, and realize many architectural styles such as large-bay,terrace-backwards and spring layers. In this paper,the central and corner local compression tests of lightweight steel and lightweight concrete walls are carried out. The failure modes of the wall and the stress variation law of lightweight steel and lightweight concrete under local pressure are analyzed. The results show that the local compression load is shared by the lightweight steel column and lightweight concrete in the compression area,which work together. The load-sharing ratio of the lightweight steel column is unchanged basically during the whole loading. Based on this,a calculation method of local compressive capacity is proposed.
