Steel Structure Building System Analysis And Its Application In Engineering

Steel structure as a kind of harmonious coexistence with nature green low carbon buildings,has been widely used in industrial and civil buildings.It has high bearing capacity,small cross section size,total weight light,low cost and high durability,optimum.Compared with reinforced concrete structure,steel structure has more resilience,ductility,deformation and energy dissipation capacity,is the first selection of high-rise buildings in the earthquake zone type..With the development of the construction technology and engineering practice experience,the steel structure of tall building is from a single whole steel structure,expand of steel and concrete mixed structure,steel reinforced concrete structure and concrete filled steel tube structure,further enhanced the wind and earthquake resistant capability of tall buildings.system Secondly based on the actual process of a steel structure building as an example,using ANSYS finite element analysis software on the numerical calculation,the natural vibration characteristics were analyzed.And chose Elcentro seismic wave,Taft wave and artificial seismic wave as the input seismic waves on the dynamic response analysis,through the dynamic time history response analysis,found the structure of the translation and the position of the torsional vibration is larger.Thus provides reference for seismic design of this kind of steel structure.Finally has xuchang airport new town 20#buildings as the research object,this paper expounds the has airport new town as a representative of component composition and mechanical characteristics of steel frame system,lateral form,wind resistance,seismic performance,design points,the node connection,etc.Engineering design personnel can project instance analysis in this paper,based on the complement each other,makes the design of high-rise steel structure is more economic and reasonable,and high-rise steel structure design level to a higher level.
