【摘要】：随着轻钢结构住宅的应用,其外围护体系的研究也不断推进,在外围护体系的发展历程中,复合墙板成为重要的一类。复合墙板具有很多的优点,但也存在一些问题,某种程度上成为制约轻钢结构住宅发展的主要因素。如今复合墙板的研究主要集中在墙板材料的革新和墙板构造两个方面,其中墙板节点构造对结构体系的抗震性能有重大影响,如果地震时墙板脱落,会对人民群众的生命财产造成严重威胁。目前国内针对复合墙板以及与轻钢结构连接节点的抗震性能研究还相对较少。因此,本文开展研究复合墙板以及复合墙板与钢结构连接节点的构造技术和抗震性能,能进一步推动轻钢结构住宅的发展与应用。本文通过采用低周往复加载试验,对复合墙板及连接节点的抗震性能进行了较为深入的研究,并利用有限元软件ABAQUS对其进行了数值模拟分析。主要成果如下:1.对复合墙板的类型以及与钢结构的连接形式进行了概述,并在前人的研究成果的基础上,提出了适用于吉林省轻钢结构体系的复合墙板和连接节点构造。并对新型的复合墙板和连接节点进行了瞻望,为往后的工程应用提供理论和试验参考数据。2.为研究复合墙板及连接节点的受力机理与破坏形式,对三块复合墙板试件进行了低周反复荷载试验研究。根据试验数据获得了(p-?)滞回曲线和骨架曲线、应力应变曲线、耗能性能、刚度退化和变形性能等,综合评价了结构的抗震性能。试验结果表明:本文新型复合墙板抗震性能好,其破坏形式主要集中在与钢结构连接的预埋件处;连接节点的性能是实现墙板与钢结构协同作用的前提,本文新型连接节点具有良好的承载能力,能够保证钢框架与墙板之间的连接安全有效。3.使用有限元软件ABAQUS对复合墙板进行了非线性有限元分析。采用Standard/Explicit建模的方法,模拟带预埋件的复合墙板在低周往复加载作用下的破坏形式。结果表明有限元模拟效果良好,结构破坏形式与试验现象基本相同,主要发生在复合墙连接节点处,但与试验相比,有限元模型产生的位移略小。4.通过与具体工程实例进行经济性对比,分析轻钢结构住宅和复合墙板的综合经济效益及其具有的优势,为今后的实际工程设计提供依据。
[Abstract]:With the application of light steel structure residential building, the research on the outer envelope system is also advancing continuously. In the development of the outer enclosure system, composite wall board becomes an important class. Compound wall board has many advantages, but there are also some problems. To some extent, it has become the main factor that restricts the development of light steel structure housing. Nowadays, the research of composite wall panel mainly focuses on two aspects: the innovation of wall board material and the construction of wall board. The joint structure of the wall panel has a significant impact on the seismic performance of the structural system. If the wall board falls off during an earthquake, At present, there are relatively few researches on seismic performance of composite wall panels and joints connected with light steel structures. In this paper, the construction technology and seismic performance of composite wall panels and joints connected with steel structures are studied, which can further promote the development and application of light steel structure houses. In this paper, the low cycle reciprocating loading test is adopted. The seismic behavior of composite wallboard and joint is studied deeply. The main results are as follows: 1. The types of composite wall panels and their connection with steel structures are summarized, and based on the previous research results, The structure of composite wall board and connection joint suitable for light steel structure system in Jilin Province is put forward, and the new type composite wall board and connection joint are forecasted. To provide theoretical and experimental reference data for engineering application in the future. 2. In order to study the mechanical mechanism and failure form of composite wall board and connection joint, the low cycle repeated load test of three composite wall plate specimens was carried out. Hysteretic curve and skeleton curve, stress-strain curve, energy dissipation performance, stiffness degradation and deformation performance are synthetically evaluated. The experimental results show that the new composite wallboard has good seismic performance. The failure form is mainly concentrated in the embedded parts connected with the steel structure, the performance of the connection joint is the premise to realize the synergistic action between the wall board and the steel structure, the new type of connection joint has good bearing capacity in this paper. It can ensure the safety and effectiveness of the connection between the steel frame and the wall board. The nonlinear finite element analysis of the composite wall panel is carried out by using the finite element software ABAQUS. The method of Standard/Explicit modeling is used to model the composite wallboard. The failure form of composite wall board with embedded parts under low cycle reciprocating loading is simulated. The results show that the finite element simulation effect is good, and the structural failure form is basically the same as the experimental phenomenon, which mainly occurs at the joint of composite wall. But compared with the test, the displacement produced by the finite element model is slightly smaller. 4. By comparing with the concrete engineering example, the comprehensive economic benefit of light steel structure residence and composite wall board and its advantages are analyzed. It provides the basis for the practical engineering design in the future.
