Nonlinear Stability Analysis of Thin-walled Pier

摘要：

The nonlinear stability of continuous rigid frame bridge with thin-walled piers is analyzed by using the current FEM software. Two aspects are included in nonlinear stability analysis. The first one, only geometric nonlinearity is considered and the other one, geometric nonlinearity and material nonlinearity are considered simultaneously. Nonlinear stability analysis during different construction stages indicates that coefficient of stability in cantilever stage is poorest. Considered the dual non-linearity, the stability coefficient descends distinctly.
