- Abstract:
- Aimed at the different loading conditions of semiintegral abutment bridges (SIAB) approach slab and common one, modified simply-supported beam method considering the effect of approach slab dimension and foundation stiffness was proposed to calculate the internal force of approach slab in SIAB based on probabilistic method and simplysupported beam method. The effective length was modified to obtain the reaction of elastic foundation and the one translated from beam to end of approach slab. Simply-supported beam method, elastic foundation beam method and modified simply-supported beam method were compared by finite element analysis. The results show that modified simply-supported beam method is more reasonable and convenient, and internal force calculation of approach slab in semi-integral abutment bridge can accord to simply-supported beam.
