| Abstract: | By analyses the construction process of a bridge transformed from simple-supported system into continous system, this paper calculates it′s creep secondary internal forces, the effects of creep on bearing force from double rubber bearing and it ′ s bearing force redistribution are analyses . At alst an examples is introduced and some important conclusions are got. |
