【摘要】：随着我国建筑业的产业发展和一系列国家政策文件的推行,可以预见在十三五期间,我国的装配式钢结构住宅将迎来巨大的发展机遇。而围护结构的相关技术问题一直是制约装配式钢结构住宅推广的一个重要原因,故作为装配式钢结构住宅围护结构重要组成部分的内墙板的相关技术的革新对于装配式钢结构住宅的发展具有重要意义。本文研究的整体式复合内墙板可以提高装配式钢结构住宅的施工效率并且能很好地解决钢梁的隔声问题,但由于其将钢梁与墙板制作形成一个整体,在工程现场同时安装就位,与常规的钢结构建筑施工先安装完毕主体结构构件后再安装墙板的受力模式有所区别。而且由于缺乏相应的规程图集或成熟的工程应用经验,故在工程应用前需对该种整体式复合内墙板进行结构性能的分析研究。本文首先通过对3块竖向荷载作用下的整体式复合内墙板开展的试验,研究分析了该种复合内墙板的破坏模式、开裂荷载、荷载-挠度曲线、各部件的应力分布情况及墙板的裂缝开展情况等。其次在试验的基础上,采用ABAQUS有限元软件建立了有限元模型,并通过有限元计算结果与试验结果的对比验证了有限元模型的准确性。最后,进行了结构性能参数化分析,研究分析了钢梁两侧混凝土墙板降口措施,墙板的混凝土强度,钢梁两侧混凝土墙板的厚度以及钢梁下XPS板的厚度等参数对该种整体式复合内墙板结构性能的影响及其规律。本文的研究成果可以为该种整体式复合墙板的应用提供理论和数据参考,对推动我国装配式钢结构住宅的发展具有重要的理论及工程意义。
[Abstract]:With the development of China's construction industry and the implementation of a series of national policy documents, it can be foreseen that during the 13th Five-Year Plan period, The prefabricated steel structure residence in our country will have a great opportunity for development, and the technical problems related to the enclosure structure have been an important reason for restricting the popularization of the assembled steel structure residence. Therefore, the innovation of the inner wall panel, which is an important part of the enclosure structure of the assembled steel structure residence, is of great significance to the development of the assembled steel structure house. The integral composite inner wall panel studied in this paper can improve the quality of the building. The construction efficiency of prefabricated steel structure residence and the sound insulation problem of steel beam can be solved very well. But because it makes steel beams and wallboards as a whole, they are installed in place at the same time at the site of the project. It is different from the conventional steel structure construction that the main structural members are installed first and then the wall panels are installed. Moreover, due to the lack of corresponding specification atlas or mature engineering application experience, Therefore, it is necessary to analyze and study the structural performance of the monolithic composite inner wall panel before engineering application. Firstly, the test of three integral composite inner wall panels under vertical load is carried out in this paper. The failure mode, cracking load, load-deflection curve, stress distribution of each component and crack development of the composite inner wall plate are studied and analyzed. The finite element model is established by using ABAQUS software, and the accuracy of the finite element model is verified by comparing the finite element calculation results with the experimental results. Finally, the structural performance parameterization analysis is carried out. This paper studies and analyzes the measures of lowering the opening of the concrete wall slab on both sides of the steel beam, and the concrete strength of the wall slab. The influence of the thickness of concrete wall slab on both sides of steel beam and the thickness of XPS plate under steel beam on the structural performance of this kind of integral composite inner wall panel and its regularity. The research results in this paper can be used for the application of this kind of integral composite wall panel. Provide theoretical and data reference, It has important theoretical and engineering significance to promote the development of prefabricated steel structure residence in our country.
