Adaptability Analysis of Conventional Internal Force Calculation Method for Approach Slab of SIAB
摘要
Abstract
The adaptability of calculation method for internal forces of approach slab in semi-integral abutment bridge (SIAB)was discussed.Firstly,the conventional bridge internal forces calculation method of approach slab was intro-duced.According to the structural characteristics of SIAB,the influence on approach slab near the abutment,due to hori-zontal force,bending moment and shear force caused by structural thermal deformation and shrinkage and creep,was ana-lyzed.Then,FEM model of approach slab of SIAB was established,and the influence of the internal forces on the ap-proach slab of SIAB was analyzed.The results show that the influence of the shear force and the bending moment is negli-gible;however,the influence of the horizontal force is significant,which would be considered in the calculation of internal force.Finally,a correction method for simply-supported beam is put forward,and a comparison of calculation methods for approach slabs between conventional bridge and SIAB is conducted,which concludes that the calculation method for calculating the internal force of approach slab in conventional jointed bridge is not suitable for SIAB.关键词
