| Abstract: |
The analysis of creep effect on steel-concrete composite structure is very complex. In this paper, the numeric analysis method of creep effect on steel-concrete composite structure with equivalent temperature field method is deduced, including transformation of initial creep strain to nonlinear equivalent temperature field along composite section, and also the reduced elasticity modulus of the concrete deck is taken for solution by computer. Based on this method, the programs for analysis of creep effect on steel-concrete composite structure with elements of integrated section without need of building models as divided separate layer have been developed, which has been used to analyse the creep effect on a long-span pre-stressed steel-concrete composite bridge. The conclusion has been drawn that creep effect is remarkable on pre-stressed steel-concrete bridge even if the reduced equivalent modulus of elasticity is considered. |
