ABSTRACT:The static analysis and comparison of two arrangement schemes for cables of steel latticed structures were performed by using finite element method.Through finite element software Midas/Gen,two kinds of steel latticed structures were compared and analyzed in terms of end reaction,deformation,node displacement and stress ratio.The correlation data of the two structures were obtained so as to illustrate the advantages of groined cables arrangement of prestressed steel latticed structures with long-span peripheral triangular pyramidal simply supports.
