摘要

The coupled shear wall system with coupling beams is one of the ideal seismic structure systems. The coupling beams with good toughness affects the seismic performance of this structural system. Therefore, ACI 318-14 Code has strict design requirements for coupling beams. This study validated the seismic performance of high-strength reinforced concrete connecting beams, and explored the configuration of different diagonal reinforcements. In this study, a total of five coupling beam specimens with a span-to-depth ratio of 1.5 were designed and subjected to repeated load tests. Under different diagonal strength of steel reinforcing bars and changes of diagonal reinforcement patterns, the response of high-strength materials applied to coupling beams is discussed. The test results show that if the high-strength coupling beam with a span-to-depth ratio of 1.5 satisfies the ACI requirements, the ultimate drift angle can reach 6%. The bundled reinforcement pattern is a feasible simplified reinforcement scheme. In addition, the use of high-strength diagonal reinforcement can effectively reduce the steel ratio and improve the construction difficulty, and the coupling beams can still maintain good seismic performance.
