Suspension bridge, one of the long span bridge type, is vulnerable to wind load. To analysis effect of wind load, this paper peformed 2D analysis for suspension bridge. Numerical model is consisted suspension bridge cross section and two nonlinear hanger cable. Suspension bridge cross section has mass and torsional resistance. Nonlinear hanger cable stiffness is bigger as displacement larger. This paper compare w/ torsional resistance model and w/o torsional resistance model. Analysis results show that w/o consider cross section torsional resistance is likely to overestimate structure response.
