Study On Seismic Behavior Of The Special-shaped Double Steel Plates-concrete Composite Shear Wall Structure System In High-rise Residential Buildings

With the impetus of the national policy,the market mechanism and many other factors,the assembly type construction with high efficiency,high quality,high yield has been more widely recognized,especially the State Council executive meeting holding in September 2016,the meeting decided to develop vigorously the steel structure,concrete and other assembly type construction,improve the proportion of assembly type construction in the new building.The assembled steel structure has the advantages of low energy consumption,less construction waste and short construction period.It is a kind of green building which is consistent with the sustainable development.This paper presents a new structural system,which is in accordance with the category of the assembly type steel structure,it's the structure system of the special-shaped double steel plates-concrete composite shear wall.In order to make it more widely used in the high-rise residential buildings,the structural system of the special-shaped double steel plates-concrete composite shear wall must be fully recognized.However,there are few studies about the structure system.Therefore,the analysis of the structural system has a certain theoretical significance and practical value.In order to effectively analyze the seismic performance of the high-rise residential buildings of special-shaped double steel plates-concrete composite shear wall structure system,this article selects a 26 layers housing of the special-shaped double steel plates-concrete composite shear wall structure system,Based on the finite element software ETABS program establishing the structure model,and the following several aspects of the study was carried out:1)The modal analysis was carried out on the structure,obtaining the dynamic performance of the structure;2)Under the effect of more severe earthquake,the dynamic elastic time history analysis was carried out through inputting the different kinds,different directions and dimensions earthquake waves,getting the structure response curve of interstory drift,interstory shear force,floor bending moment.Through the comparative analysis,obtaining the difference of seismic response of the structures;3)The structural seismic response analysis was carried out through using the response spectrum method and the time history analysis method,comparative analyzing the structure of inters-story shear force and floor bending moment,getting the differencesof the response spectrum method and the time history analysis method in this paper of the structure calculation and analysis.The comparison results provide theoretical suggestions for the seismic analysis method of the high-rise residential buildings of the special-shaped double steel plates-concrete composite shear wall structure system.
