【摘要】：现今,复合墙板在国内外建筑领域中得到了广泛的应用与研究,进而发现复合墙板与钢框架的连接节点对这种结构体系抗震性能有重要的影响,亦是保证复合墙板与钢框架共同作用、抵抗破坏的关键因素,节点的力学性能会对结构的刚度、稳定性、承载能力产生直接影响。若在地震作用下节点发生了破坏,墙板会脱落、坍塌,从而导致严重的次生灾害。目前我国关于墙板与钢框架连接节点的研究还够完善,而且连接节点样式繁多,目前在设计领域中尚未形成统一标准。因此开展复合墙板与钢框架连接节点的研究分析,对推动复合墙板钢框架结构体系在行业中的进一步发展会产生积极的促进作用。文中提出一种轻钢龙骨复合墙体与钢框架连接的新型节点,通过设计计算、单调加载试验、往复加载试验,对复合墙板与钢框架的连接节点的抗震性能进行了细致深入的研究。本文中提出了一种轻钢龙骨复合墙体与钢框架连接的新型节点,并对与连接节点相关的构造措施进行了设计说明；按照钢结构设计范中构件设计要求,验算了该连接节点设计的可行性；在单调加载试验中,采用工程中常用几种外墙龙骨板材与设计节点组合,得到组合节点在拉伸状态下的受力机理及破坏模式；对几种外墙龙骨与主体钢框架连接节点试件进行了往复荷载作用下的试验研究。主要目的是得到组合节点受力机理及破坏模式,对比了组合节点骨架曲线,分析了延性性能、耗能性能、刚度特性,试验结果表明：该种节点有良好的承载力和良好的抗震性能。
[Abstract]:At present, composite wall panels have been widely used and studied in the field of architecture at home and abroad, and it is found that the connection joints between composite wall panels and steel frames have an important impact on the seismic performance of this kind of structure system. It is also a key factor to ensure the joint action of composite wall board and steel frame and to resist failure. The mechanical properties of joints will have a direct effect on the stiffness, stability and bearing capacity of the structure. The wall board will fall off and collapse, which will lead to serious secondary disaster. At present, the research on the connection joint between the wall board and the steel frame in our country is perfect enough, and there are many kinds of connection joints. At present, there is no uniform standard in the field of design. Therefore, the research and analysis of the connection joints between composite wall panels and steel frames have been carried out. In this paper, a new type of connection between light steel keel composite wall and steel frame is put forward, through design and calculation, monotonic loading test is carried out. In the reciprocating loading test, the aseismic behavior of the connection joint between composite wall plate and steel frame is studied in detail and deeply. In this paper, a new type of connection between light steel keel composite wall and steel frame is proposed. According to the design requirements of the steel structure design model, the feasibility of the connection joint design is verified. In the monotone loading test, The mechanical mechanism and failure mode of composite joints under tensile condition are obtained by combining several kinds of external wall keel plates with design joints in engineering. In this paper, several specimens of connection joints of external wall keel and main steel frame are tested under reciprocating load. The main purpose is to obtain the mechanical mechanism and failure mode of composite joints, compare the skeleton curves of composite joints, and analyze the ductility of composite joints. The experimental results show that the joint has good bearing capacity and good seismic performance.
