Abstract:
To improve the seismic performance of reinforced concrete(RC) coupling beams with low shear span ratio, a new bolt steel plate reinforcement method and a new steel plate buckling controlled device were proposed.Three RC coupling beams with the ratio of 1∶2 were made and low cyclic loading test was done to study the effects of adhesive bolt connections on the seismic performance of RC coupling beams. The results show that the RC coupling beam without being strengthened by bolt steel plate reinforcement method presents brittle shear failure. When the RC coupling beam is strengthened by bolt steel plate reinforcement method with common highstrength bolt connections, the ductility and strength of the beam is not increased obviously.When the RC coupling beam is strengthened by bolt steel plate reinforcement method with adhesive bolt connections, the strength, deformability and energy dissipation can be increased greatly.
