Abstract

By using the finite element software ABAQUS to establish the model of industrial workshop corbel, to explore the stress state under local load, and then increase the capacity of corbel by the form of prestressing in corbels’ end. According to the stress distribution of the calculation, analysis of corbel’s normal working state and the prestressed force constraint condition in different forms comparatively. The results found that prestressing at the end of the corbel can significantly improve the ultimate bearing capacity and crack resistance of middle area. Due to the strong constraints of the prestressing, the steel strands can effectively control the deformation of the corbel in horizontal direction, the corbel crack area from the original central transfer to the upper column bending modulus is smaller, eventually destroyed.
