摘要:
提出了一种轻钢-尾砂微晶发泡板组合墙结构,首次进行了4个较小剪跨比轻钢-尾砂微晶发泡板组合墙试件的低周反复荷载试验,试件区分在于尾砂微晶发泡板强度、龙骨间是否填充砌块及有无拼接板缝。分析了各试件的强度、刚度、延性、滞回特性、耗能能力及破坏特征。研究结果表明:轻钢与尾砂微晶发泡板具有良好的共同工作性能;弹性阶段尾砂微晶发泡板呈剪切变形,且其变形发展受轻钢龙骨和镶嵌的分布钢筋制约;尾砂微晶发泡板强度可以明显提高结构的承载力;构件拼缝对结构的承载力有降低作用;轻钢龙骨间填充轻质砌块可显著提高其抗震性能。
Abstract:
A light steel-tail sand microcrystalline foam board composite wall structure was proposed. The low-cycle repeated load test of four small shear-to-span light steel-tail sand microcrystalline foam board composite wall specimens was carried out for the first time. The difference between the pieces is the strength of the tailings microcrystalline foaming board, whether the keel is filled with blocks and whether there are splicing slats. The strength, stiffness, ductility, hysteresis characteristics, energy dissipation capacity and failure characteristics of each test piece were analyzed. The results show that the light steel and tailings microcrystalline foaming board have good working performance; the elastic phase tailings microcrystalline foaming board is shear deformation, and its deformation development is restricted by the light steel keel and the inlaid distribution steel; The strength of the tailings microcrystalline foaming board can significantly improve the bearing capacity of the structure; the joints of the components can reduce the bearing capacity of the structure;The steel keel filled with lightweight blocks can significantly improve its seismic performance.
