The paper studye the effect of shrinkage and creep on the cable-stayed suapension bridge. In order to research the static action of cable-stayed suspension bridge, two plane models of Jinzhou Bay Bridge is analyzed under shrinkage and creep by using general FEM software. One is a self-anchored bridge and the other is an earth-anchored bridge. The differences in static behavior between the two bridges are compared in detail. The results indicated that the shrinkage and creep effects have great influences on both bridges, and the effects have greater influences on self-anchored system than earth-anchored system. In addition, the author analyzes the causes of these differences between the two bridges. In conclusion,shrinkage and creep have some effect on the bridge displacements and internal forces. It is an important factor which can not be ignored in the design.
