【摘要】：钢结构住宅是值得现代住宅结构所应该大力发展的住宅结构形式，具有传统钢筋混凝土结构住宅诸多不具备的优点。随着我国钢材产量的不断提高，经济的不断发展，钢结构住宅由于其良好的施工速度，优质的住宅环境，符合可持续发展的绿色环保节约的施工特性，拥有了较多的建造需求。在推广钢结构住宅的进程中，有必要对钢结构住宅的各项力学性能与经济性能有较为清晰的认识，从而更好的使钢结构住宅的建造得到更为有利的发展。本文针对小高层钢结构住宅的抗震性能与经济性进行研究。选取纯钢框架结构,钢框架支撑结构和钢框架-混凝土核心筒结构三种结构形式对其进行结构设计和静动力弹塑性分析，并对钢结构住宅和钢筋混凝土结构住宅进行了经济性的对比。结构的抗震性能通常包括结构在小震弹性阶段在地震作用下的状态和在大震弹塑性阶段在地震作用下的状态。本文在对三种结构进行了弹性阶段的振型分解反应谱分析与弹性时程分析，获得了三种结构在多遇地震作用下的抗震特点。同时本文对三种结构进行了罕遇地震作用下的静力弹塑性分析和动力弹塑性分析，获得了三种结构在罕遇地震作用下的抗震特点。结构局部性质通常会影响结果整体的抗震性能。本文对纯钢框架结构研究了节点半刚性对抗震性能的影响，总结出节点刚度对抗震性能的作用。对钢框架支撑结构研究了偏心支撑耗能梁段长度对整体结构抗震性能的影响，获得了耗能梁段长度对抗震的作用。结构的经济性研究不仅包含了直接造价，也包含了在施工和使用过程中结构的施工与使用特点所带来的其他效益。本文基于钢结构住宅和钢筋混凝土结构住宅直接造价的对比，，并综合考虑了综合效益的影响，总结出钢结构住宅具有良好的经济性和优良的发展前景。
[Abstract]:The steel structure residence is the residential structure form which should be vigorously developed by the modern residential structure. It has many advantages which the traditional reinforced concrete structure residence does not have. With the continuous increase of steel production in our country. With the continuous development of economy, the construction characteristics of steel structure housing are in line with the sustainable development of green environmental protection because of its good construction speed and high quality residential environment. In the process of popularizing steel structure housing, it is necessary to have a clear understanding of the mechanical and economic properties of steel structure housing. In order to make the construction of steel structure housing more favorable development. In this paper, the aseismic performance and economy of small high-rise steel structure residence are studied. The pure steel frame structure is selected. Structural design and static and dynamic elastoplastic analysis of steel frame braced structure and steel frame-concrete core tube structure are carried out. The economic comparison between the steel structure residence and the reinforced concrete structure house is also carried out. The seismic behavior of the structure usually includes the state of the structure under seismic action in the elastic stage of small earthquake and the state of the elastic-plastic stage of the large earthquake. In this paper, three kinds of structures are inversely decomposed in the elastic stage. Spectrum analysis and elastic time history analysis. At the same time, the static elastoplastic analysis and dynamic elastic-plastic analysis of three kinds of structures under rare earthquake are carried out. The seismic characteristics of three structures under rare earthquake are obtained. The local properties of the structure usually affect the overall seismic performance of the result. In this paper, the effect of joint semi-rigidity on the seismic performance of the pure steel frame structure is studied. The effect of joint stiffness on seismic performance is summarized. The effect of beam length of eccentrically braced energy dissipation on the seismic behavior of the whole structure is studied for the steel frame bracing structure, and the effect of the length of energy dissipation beam section on the seismic behavior of the whole structure is obtained. The economic research of structure includes not only the direct cost. It also includes the other benefits brought by the construction and use characteristics of the structure during the construction and use. This paper is based on the direct cost comparison between the steel structure residence and the reinforced concrete structure residence. Considering the influence of comprehensive benefit, it is concluded that steel structure residence has good economy and development prospect.
