Analysis of Nonlinear Stability of Single Alluminium Alloy Layer Latticed Domes

An analysis of nonlinear stability of single layer latticed domes has heen carried out based on fi- nite element analysis space beam element. Eigenvalue Buckling method is used to predict the theory buck- ling strength of construct and to obtain the buckling mode. Through arch-length method, the complete- process analysis of construct displacement is studied and the critical load obtained. The stability of single alluminium alloy layer latticed domes under different loads and constrans is studied in details.
