Abstract

Local stress of steel-concrete joint section is analyzed in the role of three conditions. According to the engineering example of Weihe grand bridge, the finite element space model of steel-concrete joint section is built. Through calculation and analysis, the stress state of steel-concrete joint section is analyzed under three load conditions. The results show that stresses meet all the requirements of design except that the stress concentration occurs at the bottom of concrete box beam by the side of the bearing plate and at the area prestressed tendon anchored. And part of tensile stress exceeds tensile strength of concrete at corner of concrete box beam floor and roof. With continuous and coordinated deformation, the design of steel-concrete joint section is safe and reliable, realizing the smooth transition of stiffness. Considering the complex stress of steel-concrete joint section, it is proposed to add proper tensile fiber in the concrete in steel-concrete joint section to improve performance of structure.
