Abstract
To perfect the calculation formula of concrete local compression bearing capacity for the current code, which has no considering the influence of longitudinal-steel in beam, longitudinal-steel in column and stirrup, the positive influence of steel in beams and columns in the local compression bearing capacity calculation, and the thought that reinforcement intersected with anchor plate in beams and columns can be regarded as equivalent plate are put forward. The analysis result shows that the equivalent new added local compression area of reinforcement in beams and columns in node can be taken as the projected area of 3 times of the diameter of steel bars in the direction of prestressed bars. Based on the analysis, the calculation formula of local compression area and calculated bottom area, and the calculation method of local compression bearing capacity considering the effect of longitudinal-steel in beam, longitudinal-steel in column and stirrup are put forward.
