Hangers of self-anchored suspension bridges are generally installed after temporarily supporting girders. Hangers are installed with initial tension, then hangers can be exposed to greater than that of final stage during the sequence of construction. Therefore it is required that the tension of hangers should be within the allowable capacity. This study presents the nonlinear analysis method to simulate the construction sequence of self-anchored suspension bridge. The tension variation of hangers according to the sequence and method of construction is studied.
