Abstract

Through the calculation and analysis on the stress state of deep corbel under local compression, reinforce deep corbel by external prestressing form. According to the calculation results, find the difference between the stress distribution constrained by prestress and that of normal working state, analysis on the influence of different position on the ultimate bearing capacity. The working mechanism of deep corbel and ordinary corbel are basically the same. The concrete at the middle area of corbel constrained by prestress strongly, Its ultimate bearing capacity and crack resistance increased significantly. With the position of prestressed constraints changing, the ultimate bearing capacity of deep corbel also changes. The ideal constrained position is located in the central of deep corbel.
