Normal Section Bearing Capacity of Reinforced Concrete Frame Joints with Open Floor Corner

Abstract:

Consider the floor slab reinforced by the increases of the bending capacity of the negative moment on the beam end, the derivation of the nodes under the floor and beam together calculation of bearing capacity formula. Calculate and compare ordinary floor and the floor to the bottom of the beam end and end-column section bearing capacity open-angle seam. The results show that the slit in the floor open-angle measures, due to the reinforcement in the slab near the beam end is cut off, the beam end flexural capacity reduced by 19%, the column end bearing capacity is very small, the bearing capacity of the beams side of the gap increases, the does not affect the bearing capacity of the premise to ensure strong column and weak beam seismic requirements.
