Structural Analysis on Double-layers Steel Lattice ShellPENG Shao-min1,ZHOU Fei2(1.School of Architecture and Civil Engineering,Wuhan University of Technology,Wuhan 430070,China;2.Higher Education Architectural Design and Plan Institute of GD Pro,Guangzhou 510631,China)Utilizing the finite element analysis software-ANSYS,this article designs a special double-layers lattice shell base on geometric model of parameters and selects the area of the bar on the basis of the danger case.Then the static analysis and the stability analysis are carried out on the basis of the selected bar.The whole process leads to the benefit conclusion for the design of the lattice shell.double-layers lattice shell;parameter design;static analysis;buckling eigenvalue
