Using the development tool APDI, language and element capability of birth and death in ANSYS, the construction state of Jingzhou bridge is simulated in the paper. Two stages, the longest single-cantilever and twin-cantilever, are selected to analysize the individual influence of different sources of nonlinear factors (the large deflection, beam-column and cable sag effects). Results show that the coupled effect of three geometrical nonlinear factors is not the simple sum of individual factors, which should be considered comprehensively. The nonlinear contribution by large deflection is the mos...
