摘要
轻钢轻混凝土剪力墙是轻钢轻混凝土结构体系的主要结构构件。本文介绍了以剪跨比为试验参数的轻钢聚苯颗粒混凝土剪力墙低周往复加载试验及其试验结果,分析了剪跨比对剪力墙的承载能力、变形能力和耗能能力等抗震性能的影响。研究结果表明:剪跨比对轻钢聚苯颗粒混凝土剪力墙的破坏模式的影响明显,且不同剪跨比试件均显示出良好的变形能力和耗能能力。
Lightweight steel and expanded polystyrene concrete shear walls are the main structural members for lightweight steel and lightweight concrete structure system. In this paper, the static cyclic test results of lightweight steel and expanded polystyrene concrete shear walls are introduced, which are constructed by shear span ratio as the experimental parameter. Then, the effects of shear span ratio on seismic capacity of shear walls, such as loading capacity, deformation capacity and energy dissipation capacity, are analyzed based on the test results. It is clarified that shear span ratio has an obvious effect on failure mode, and all specimens show better deformation capacity and energy dissipation capacity with the increase of shear span ratio.
