Abstract

In this paper, an analysis program is developed by the finite element method, which considers geometric nonlinearity as well as snap-through buckling in optimization of space trusses. A numerical analysis technique for nonlinearity is used to modify the incremental method and the displacement incremental method. In order to illustrate the optimization of space trusses considering snap- through buckling, an illustrative example is presented. 1 Introduction Recently, steel space trusses and network domes have become popular in the design of gymnasiums, exhibition halls and other similar buildings which enclose open space truss envi
