[Abstract]:Double-plate-concrete composite shear wall houses have the advantages of light weight, excellent seismic performance, fast construction speed, high utilization rate, and flexible wall arrangement. Under the background of promoting the development of green building and removing overcapacity of steel structure, the government strongly advocated the prefabricated housing, promoted the development of green building of steel structure and eliminated overcapacity. Composite shear wall housing has a broad prospect of development. Based on a new type of double steel plate composite shear wall proposed by our team, this paper makes a comparative analysis of the model building and structural performance of this kind of structure when it is applied to high-rise residential buildings. It provides a strong design basis and theoretical guidance for the practical application of this kind of structural system and promotes its healthy and rapid development. The equivalent stiffness method is introduced and the equivalent formula for converting the mixed wall with this material into a single material wall is derived. According to the ultimate state theory of compression and bending members, the whole stability analysis of composite wall is carried out, and the local stability of composite wall is analyzed by energy method. The seismic grade of composite wall is analyzed by referring to the current structural design code and combining with the previous theoretical study. The value of composite wall thickness and steel plate thickness is discussed. The double steel plate composite shear wall was applied to a 32-story house and the structure was designed. The equivalent model was established by using the method of equivalent stiffness modeling and the actual model was established by finite element software. In order to explore the error and feasibility of the equivalent stiffness modeling method, a comparison model of steel frame-braced structure and steel frame-steel plate wall structure is established on the basis of the above engineering background, and the modal analysis is carried out. The relationship between the mode participation coefficient and the structural response is discussed, and the influence value and law of the higher-order mode are studied, and the response spectrum analysis, elastic time history analysis and elastic-plastic stage nappe analysis are carried out. The aseismic characteristics of double-plate-concrete composite shear wall structure and other two structural systems are obtained. The wind load effect and economic efficiency of each structural system are analyzed. In this paper, the calculation and comparison of the steel quantity used in the double-plate-concrete composite shear wall structure, the steel frame-braced structure and the steel frame-steel plate wall structure are carried out by using the steel structure calculation software STSL.
