【Abstract】 Abstract In this paper, the theoretical analysis on non - linear behaviuor of the single dome structures is presented. In order to trace effectively equilibrium configration of the structures , a new tactics on structures calculate is made and corresponding restrained equation and automatical equation for initial load incremental length is set up. A finite element method computer program for stability analysis has been completed.In order to check reliability of this analytal results of theory, two exemplification has been analyzed. This calculation results fitted with reference ones very well.更多还原
