装配式钢骨架-轻骨料复合墙板抗震性能试验研究
Seismic Performance of Assembled Steel Skeleton-Lightweight Aggregate Composite Wall Panels
本文研发了一种新型装配式钢骨架-轻骨料复合墙板,该墙板将陶粒珍珠岩混凝土填充于钢骨架内作为保温材料,形成集保温和承重功能于一体的新型复合墙板。为研究该墙板的抗震性能,对3个墙板试件和1个钢骨架试件进行低周往复加载试验,分析了在一定轴压比下槽钢尺寸、钢筋网布置数量、是否填料等因素对试件破坏模式、水平承载力、刚度和耗能能力的影响。试验结果表明:该墙板具有较高的水平承载力、刚度和耗能能力,轻骨料混凝土与钢骨架之间具有较好的结合效应;墙板试件的破坏表现为面层脱落、墙板开裂以及槽钢变形屈服;钢骨架试件的破坏表现为槽钢弯曲变形、钢筋网弯曲断开;减小槽钢厚度和槽钢翼缘宽度会降低墙板的水平承载力、初始刚度和耗能能力;钢筋网布置2片比布置1片的试件水平承载力高、初始刚度大、耗能能力好;未填料的钢骨架试件水平承载力、刚度和耗能能力均低于墙板试件的水平承载力、刚度和耗能能力。基于墙板试件的试验结果,提出了装配式钢骨架-轻骨料复合墙板抗剪承载力的计算公式,计算结果与试验结果吻合较好。
A new type of assembled steel skeleton-lightweight aggregate composite wall panel is developed. The ceramic perlite concrete is filled into the steel skeleton as thermal insulation material to form a new composite wall panel that integrates thermal insulation and load-bearing. In order to study the seismic performance of the wall panel, a low-cycle reversed loading test was carried out on three wall panel specimens and one steel skeleton specimen, and the effects of channel steel dimension, the number of reinforcing mesh layers and whether or not the steel skeleton was filled were analyzed on the failure mode, lateral bearing capacity, stiffness and energy dissipation capacity of the specimens under a certain axial compression ratio. The test results show that the wall panel has higher lateral bearing capacity, stiffness and energy dissipation capacity, and the lightweight aggregate concrete and steel skeleton exhibit good bonding performance. The failure of the wall panel specimen is manifested as surface layer spalling, wall panel cracking and yielding deformation of channel steel. The steel skeleton specimen shows the bending deformation of channel steel and the bending fracture of reinforcing mesh. The lateral bearing capacity, initial stiffness and energy dissipation capacity of the wall panel decrease with the reduction of the thickness of the channel steel and the width of the channel flange. The lateral peak bearing capacity, initial stiffness and energy dissipation performance of the specimens with two layers of reinforcing mesh are higher than those with one layer of reinforcing mesh. The lateral bearing capacity, stiffness and energy dissipation of the unfilled steel skeleton specimen are lower than those of the composite wall panel specimen. Based on the test results, a formula for calculating the shear strength of the assembled steel skeleton-lightweight aggregate composite wall panel is proposed. The calculation results are in good agreement with the test results.
