The High-rise Steel Structure Of The Three-dimensional Garage

With the rapid social development and explosion of the car ownership，the problem ofstatic is even more acute. People is becoming care of the problem about how to solve parkingdifficult.，and using the three-dimensional garage of small space required and high parkingdensity is reach a consensus. This paper has discussing the mechanical property about steelstructure of the three-dimensional garage，and studying the influence of steel structure of thethree-dimensional garage about different number of plies、different structure form，including thesecontent：This article reference the related building codes and automotive related library designstandard，and suggesting some methodology about steel structure of the three-dimensionalgarage designing、each basic parameters，just like story height、garage load and so on.This paper analysis static force about the basic unit of steel structure of thethree-dimensional garage，and studying the influence of structure about different number ofplies，using sap2000to study structure of displacement and stress.Studying the influence of structure about different form of organization by increasingthe basic unit and increase the vertical support.Using modal and pushover to analysis three kind of structure，and contrasting toearthquake resistant behavior of three kinds of structure.The results of the study show that：Structure of the component selection decided tostructure stiffness，and single library steel structure three-dimensional garage with structurehighly increased，the section increasing。When Structure increase To a certain height，thecomponent stress become dropped，and economic decline，so the structure design is not proneto more than11layer. Increased structural units, structure lateral decreases, and overallrigidity increases, the seismic performance improved. Structure increases lateral support, the structure stiffness improved obviously, increase beam-column stress, material utilizationincreases, the seismic performance improved. The design of the structure by structure stiffnesscontrol, change the structure of form can improve the structure design level...
