Abstract:Based on the finite displacement theory and considering mechanical properties of self-anchored cable-stayed suspension bridge, the nonlinear factors, including sag of cable, large displacement, initial internal force, axial forces-bending moment interaction, concrete shrinkage and creep and loss of pre-stress, are fully considered, and the finite element method suitable for nonlinear analysis of self-anchored suspension bridges is presented in this paper. Through detailed analysis of a self-anchored cable-stayed suspension bridge with span of 400 m by using the finite displacement theory, a series of conclusions about self-anchored cable-stayed suspension bridge mechanical properties are drawn.
