| Abstract: | Based on proposing hybrid material frame element concept of concrete filled steel tube (CFST) structures, with time dependent and composite characteristics effectively considered, this paper proposes geometrically nonlinear analysis method of CFST bridges. A verifiable example is followed, which analyzes the influential extent of the geometrical nonlinearity by comparison of linear analysis. |
