Stability Study of Self-Balanced Prestressed Latticed Shell Structure with Large Span

In allusion to research status that structure stability performance of Self-balanced prestressed latticed shell assembled with elements is not explicit, using the finite element analysis method study structure stability to a large span latticed shell. The eigenvalue buckling analysis of latticed shell use Block-Lanczos method, and nonlinear analysis adopt consistent mode imperfection method. Through the contrast analysis from buckling load, buckling modes, degree of prestress, different initial disfigurement in latticed shell structure, obtaining the disciplines that structure stability properties of the large span prestressed latticed shell, related conclusions to the engineering design of new latticed shell are instructive.
