【摘要】：随着我国城市化和工业化的飞速发展,住宅工业化将成为未来住宅发展的必经之路,预制装配整体式混凝土结构是实现住宅工业化的有效途径。基于此种结构的推广,本文的主要一下几个方面的内容： (1)总结了现有比较好的几种预制装配式框架结构的构造方式以及它们的主要受力特点,包括叠合梁、叠合板的受力及构造,叠合梁—板节点的受力和构造,现浇柱叠合梁节点的受力及构造,主次梁节点的受力和构造。 (2)归纳整理了预制装配整体式框架结构的设计理论和设计方法,包括主要受力构件梁、板、柱的设计和验算。通过乐山市水口工业集中区公共租赁房项目的工程实例,总结了装配整体式框架结构的设计流程,为设计方提供一个参考；并且研究整理了预制装配整体式框架结构预制构件的生产工艺流程以及施工现场的安装工艺流程,为施工方提供一个参考。这一系列工作使设计、生产、施工构成一个整体,为此种结构的应用推广提供参考依据。 (3)使用SAP2000有限元分析软件对分别对三种外墙形式(普通砌体填充墙、预制外墙外挂式连接和预制外墙侧连式连接)进行了反应谱分析,通过比较几种外墙形式下框架结构自振周期和层间位移的变化,分析它们对框架结构刚度的影响,进而对框架结构整体性和抗震性的影响。通过分析结果,得出使用预制外墙侧连式连接的框架结构整体性和抗震性都较其他形式的外墙更优,并且这种影响较大,不可忽略。因此对目前使用的装配整体式框架结构的设计方法提出质疑。
[Abstract]:With the rapid development of urbanization and industrialization in China, housing industrialization will become the only way to the future housing development. Precast and assembled integral concrete structure is an effective way to realize housing industrialization. Based on the generalization of this structure, the main contents of this paper are as follows: In this paper, the author summarizes several existing prefabricated frame structures and their main mechanical characteristics, including superimposed beams, laminated plates, composite beam-plate joints. The stress and structure of cast-in-situ column composite beam joint and the force and structure of primary and secondary beam joint. The design theory and design method of precast assembly integral frame structure are summarized, including the design and checking calculation of the main load-bearing member beam, plate and column. Through the engineering example of the public rental house project in Shuikou industrial concentration area of Leshan City, the design process of assembling integral frame structure is summarized, which provides a reference for the designer. The production process of prefabricated assembly integral frame structure and the installation process of construction site are studied and sorted, which provides a reference for the construction side. This series of work makes the design, production and construction form a whole, and provides a reference for the application and popularization of this kind of structure. The response spectrum of three types of external walls (common masonry wall, prefabricated external wall external connection and prefabricated external wall side-connected connection) is analyzed by using SAP2000 finite element analysis software. By comparing the changes of natural vibration period and floor displacement of frame structure under several external wall forms, the influence of them on the stiffness of frame structure and on the integrity and seismic resistance of frame structure are analyzed. Based on the analysis results, it is concluded that the integrity and seismic resistance of the frame structure with precast external wall connection are better than those of other external walls, and the influence is great and can not be ignored. Therefore, the design method of assembly integral frame structure used at present is questioned.
