摘要:
为了研究基于钢板连接的夹芯墙板-钢框架体系的抗震性能,首先对钢板连接下的夹芯墙板与钢框架进行了抗剪性能试验,研究了连接钢板的抗剪性能,然后进行了1榀连接钢板厚度为3 mm夹芯墙板钢框架体系、1榀连接钢板厚度为6 mm夹芯墙板钢框架体系和1榀对比空框架体系的低周往复试验,分析了各试件的失效模式、滞回性能、耗能能力以及刚度退化规律等,最后综合评价其抗震性能。结果表明:连接钢板的平均抗剪承载力为59.8 kN,并且连接钢板的焊接质量会影响其受力性能,造成墙板框架体系正负向极限承载力的不对称,最大相差达到25.1%; 当连接钢板较薄时,连接件撕裂与开焊,除连接件附近混凝土开裂外,墙板基本完好; 当连接钢板较厚时,连接件基本完好,墙板斜对角开裂破坏,加厚钢板虽能提高体系的初始刚度,但延性有所降低; 增设墙板能提高主体框架的承载力、延性与耗能能力等,并且墙板与钢框架之间协调变形,表现出良好的整体性; 当水平位移较大时,墙板与框架形成对角斜撑机制; 研究成果可为后续开展夹芯墙板与框架相互作用机理的研究提供理论指导。
Abstract:
In order to study the seismic performance of sandwich wallboard-steel frame system based on steel plate connection, the shear performance test of sandwich wallboard and steel frame under steel plate connection was carried out, and the shear performance of the steel plate connection was studied. Then, one steel frame system of sandwich wallboard with thickness of 3 mm, one steel frame system of sandwich wallboard with thickness of 6 mm and one contrastive empty framework system were studied by low cycle reciprocating test. The failure mode, hysteretic performance, energy dissipation capacity and stiffness degradation of each specimen were analyzed. Finally, the seismic performance was evaluated comprehensively. The results show that the average shear capacity of the connecting steel plate is 59.8 kN, and the welding quality of the connecting steel plate will affect its mechanical performance, which will cause the asymmetry of the positive and negative ultimate bearing capacity of the wallboard frame system, with the maximum difference of 25.1%. When the connecting steel plate is thin, the connecting parts are torn and welded, except for the concrete cracking near the connecting parts, the wallboard is basically in good condition. When the connecting steel plate is thick, the connecting parts are basically intact and the wall plate cracks diagonally. In addition, the thickening steel plate can improve the initial stiffness of the system, but the ductility is reduced. Adding wallboard can improve the bearing capacity,ductility and energy dissipation capacity of the main frame. And the coordinated deformation between wallboard and steel frame shows a good integrity. When the horizontal displacement is large, the diagonal oblique brace mechanism is formed between the wallboard and the frame, which can provide theoretical guidance for the subsequent research of the interaction mechanism between the sandwich wallboard and the frame.
