Seismic Performance on Reinforced Concrete Frame Joints of Open Set Corner Floor
Quasi-static analysis of in-situ reinforced concrete frame joints is done by using finite element software ADINA. The calculation results of the ordinary beam-column joints and the surrounding floor located Corner joints are compared. It is shown that near the beam ribbed slab reinforcement stress significantly increases with the loading displacement increasing, indicating that the floor enhance the flexural capacity of beam. On the conditions of no influence the joint strength, floor set corner can be partially weakened the capacity of the beam flexural, and reinforcement of beams yield significantly in advance. When the beam reinforcement yield, the column of concrete cracks have also been reduced. Meanwhile, the beam-end and column-end plastic hinge appears increase the time interval, so that the joints are closer to the characteristics of the beam hinge mechanisms by the earthquake damage.
