- Abstract:
- Based on the results of the static loading test on the four RC Beam - column’s Joints Strengthenedby gluing steel plates and the two RC Beam - column ’s Joints without being strengthened by gluing steelPlates,the strain of the tensile steel and the strain of steel plates in the negative moment region of the girderends and the deflection of midspan with four different kinds of anchoring methods under the action of the staticload are analyzed. The results show that the corner stiffness of the steel plate and beams and the strength of theHoop board in the corner of columns are the main factors leading to different anchor effect in the test,and in-creasing the corner stiffness of the steel plate can fulill to the ability of the steel plate better，and the actualreinforcement effect can also better satisfy the design requirement of reinforcement effect.
