Study On The Impact Of Internal Force Of Large Basement Roof On Shear Walls Surrounding Residential Building With Horizontal Earthquake Action

With the rapid development of economy in China, automobile industrydevelopsfast and automobilenumberincreases rapidly.Chassis Tower high-rise buildings cropup in the residential district, and have the development tendency of more turrets andlarger site. When we perform calculations on the basement of high-rise building,it iswidespread concerned in what is the relationship between basement roof and thetowers. Through the basement roof, horizontal seismic ground motion acts on theshear walls surrounding the towers, which were concentrated forced.Therefore, In theprocess of calculating, study on roof of the basementand thebuildings is verynecessary. Based on previous research,the main work of this thesis is about theanalysis of several engineeringin Tianjin.Firstly，analyzing the YJK and PKPM，we determine the feasibility of YJKstructural calculations.Then,according to analysis two large high-rise residentialbuildings in Tianjin，webuild dislocation model and dislocation-free model betweenbasement roof and floor slabs，research of structure internal force under the action ofEarthquake in X direction、down-X direction、up-X direction、Y direction、 right-Ydirection and left-Y direction. With horizontal earthquake action, we analysistheinternal forces of shear walls by basement roof acting on.According to the results,weget relevant conclusions, and make recommendations on actual engineering.
