【摘要】：在全面建成小康社会的关键阶段,高层钢结构住宅成为最具影响力的民用建筑推广模式。同国外发展相比,我国钢结构住宅起步较晚,结构设计与建造技术较为落后。钢结构住宅具有许多优势和特点,其结构抗震性能佳,抗风性能强,安全可靠,综合造价低,施工便捷工期短。据行业调查,同一建筑物采取不同的结构形式进行施工,混凝土结构要比钢结构工期可超出1/3,同时可以实现拆除后100%回收钢材,绿色环保,实现循环利用,符合国家可持续发展的要求。可见,钢结构住宅的出现和发展,已经使我国房地产乃至整个建筑行业踏上了新征程。通过翻阅大量文献,收集相关行业资料,研究主要以高层钢结构住宅为对象,阐述高层钢结构的发展现状,并指出钢结构作为住宅结构体系的优势以及高层钢结构不同结构体系住宅在国内外的发展状况,归纳钢结构自身优点和存在的问题。分析高层钢结构住宅结构各种体系的设计应用,剖析三种不同结构内在形式和各自优势和对抗震设计理念做出详尽分析。建立模型布置方案,运用有限元设计分析软件PKPM计算并分析在同一地区以纯钢框架、钢框架—支撑、钢框架—剪力墙三种各异的结构三维模型,得出在地震作用下三项结构体系各项数据的差别。最后通过反应谱分析和时程分析得出的分析结构的振型与周期、结构的最大位移、层间位移、层间位移角、顶点位移、顶点位移加速度数据(结构整体稳定分析)、剪重比,得出高层钢结构住宅在不同情况下结构选型的优先性,并且对于钢结构住宅产业化发展提出建议和意见。并在此研究基础上,为以后相关课题深入研究提出一些亟待解决的难题。
[Abstract]:In the key stage of building a well-to-do society in an all-round way, high-rise steel structure housing has become the most influential mode of civil building promotion. Compared with the development of foreign countries, the steel structure residence in our country started relatively late. Structural design and construction technology is relatively backward. Steel structure housing has many advantages and characteristics, its structure seismic performance, strong wind resistance, safety and reliability, low comprehensive cost, short construction period. According to industry survey. The construction of the same building takes different structural forms, the concrete structure can exceed 1 / 3 of the time limit of the steel structure, at the same time, 100% steel can be recovered after demolition, green environmental protection and recycling can be realized. Meet the requirements of national sustainable development. It can be seen that the emergence and development of steel structure housing has made our real estate and even the entire construction industry embarked on a new journey. The research mainly takes the high-rise steel structure residence as the object, expounds the development present situation of the high-rise steel structure. It also points out the advantages of steel structure as a residential structure system and the development of high-rise steel structure housing with different structure systems at home and abroad. The advantages and problems of steel structure are summarized, and the design and application of various systems of high-rise steel structure residential structure are analyzed. This paper analyzes the internal forms and advantages of three different structures, and makes a detailed analysis of the seismic design concept, and establishes a model layout scheme. Using the finite element design and analysis software PKPM to calculate and analyze the three kinds of three-dimensional models of steel frame, steel frame-braced and steel frame-shear wall in the same area. Finally, through response spectrum analysis and time history analysis, the vibration pattern and period of the structure, the maximum displacement of the structure, the interstory displacement, and the displacement angle between the layers are obtained. Vertex displacement, Vertex displacement acceleration data (structural stability analysis, shear weight ratio, the structure of high-rise steel structure in different cases of the choice of priority. On the basis of this research, some problems that need to be solved are put forward for further research.
