钢梁—钢筋混凝土柱组合框架结构节点设计方法的研究
|
摘要
组合结构也称复合结构或混合结构,它是一种能充分发挥不同材料特性和不同结构性能的结构体系。钢梁-钢筋混凝土柱组合框架结构体系(RCS组合结构)能够充分发挥钢材和混凝土材料各自在结构上以及经济上的优势,因而获得了越来越多的研究和应用。RCS组合结构节点由于其构造及传力的复杂性,有必要对其受力性能和设计方法进行进一步的研究。
本文主要针对“钢梁贯通式”节点详细分析了RCS组合结构节点的各种不同的构造处理方法,对RCS组合结构节点的受力机理进行了深入的研究,提出了节点的受力模型,并指出其承载力主要由节点内部抵抗机构和外部抵抗机构共同承担,其中内部抵抗机构是主要的受力部分,分析了不同的构造元素在节点传力过程中所起的作用,提出了构造上的设计建议。另外还根据试验资料对节点区变形和层间位移的构成以及各部分变形在总变形中所占的比重进行了分析。
RCS组合结构节点在外力作用下存在节点区域剪切破坏以及节点混凝土受压破坏两种破坏形式。本文搜集了国内外业已完成的RCS组合结构节点的试验资料,加以分析研究,并结合型钢混凝土结构节点的设计方法以及已有的RCS组合结构节点的研究成果,推导了RCS组合结构节点在这两种破坏模式下的承载力计算公式,并利用试验结果数据对计算公式的精确程度及适用性进行了验证,同时结合试验资料分析了不同节点构造对其承载力的影响。
本文运用ANSYS软件分析了不同节点构造形式对RCS组合结构节点受力性能的影响,主要考虑因素为面承板的不同构造形式以及钢环箍的设置等。分析表明,面承板是RCS组合结构节点不可或缺的重要构造措施,而设置延长式面承板、扩展式面承板或钢环箍可以更加有效地提高节点的承载力和刚度。
Composite structures is also called complex structures, it can utilize the different material characteristics and structural performances sufficiently. The composite frame structural system with RC columns and steel beams can effectively utilize the structural and economic advantages of both steel and concrete materials, and it has gained more and more research and application. Because of the complication of the constructional details and force transferring of RCS composite joints, more research is necessary to improve better understanding of their behavior and design method.
In this paper, the various details of RCS composite joints and force transfer mechanisms with "through beam type" are studied, a model to predict the behavior of RCS joints is presented, it is believed that the joint strength is composed of the contributions of the inner element and outer element, where the inner element is the main force resisting part, the effect of different RCS composite joints details in force transferring is analyzed and the suggestion on joints details is presented. The components and component ratio of joint deformation and story drift are also analyzed.
A panel shear failure and a bearing failure are identified in RCS composite joints. In this paper, experimental data of RCS composite joints are arranged and studied, referring to the design method of SRC composite joint and the research production on RCS composite joint, the design method of RCS composite joint with the two failure mode are deduced, the accuracy and applicability of the proposed design equations are examined by comparing with available experimental data, various factors that influence the strength of RCS joints are analyzed according to the experimental and calculated data.
By the finite element analysis program ANSYS, the influence of various joint details on the behavior of RCS joints is studied, parameters considered include different details of face bearing plate and steel band plate, etc. Analysis results show that face bearing plate is a very important detail of RCS joints, and extended face bearing plate、wide face bearing plate or steel band plate can improve the strength of RCS joints more effectively.
