剪压比影响下配置HRB500E钢筋梁柱节点试验研究
Experimental Research in Influence of Shear-compression Ratio on the Interior Beam-column Joint with HRB500 E Reinforcements
摘要
Abstract
Since high performance reinforcements (HRB500E) have the advantages of better ductility and earthquake-resistant behavior,this paper focused on the seismic behavior of interior RC beam-column joints with HRB500E reinforcements. Three full-scale interior beam-column joint specimens were tested to failure under quasi-static load. The influence of shear-compression ratio on the failure mode, hysteretic characteristic and ductility behavior of interior RC beam-column joints were investigated. The results indicate that interior RC beam-column joints with HRB500 E reinforcements generally have a good seismic behavior. To be more specific, as the shear-compression ratio increases, the failure of the specimens changes from flexural failure of beam end to shear failure of joint core; the area of hysteretic curve increases greatly, and at the later stage of the loading, the peak load of hysteretic loop decreases rapidly. In the meantime, the yield load and the maximum load increase, the yield displacement also increases as well, which leads to the decrease of ductility coefficient of the joints.关键词
