| 摘 要： | 为研究超高韧性水泥基材料新型梁柱节点的抗震性能,进行了6榀缩尺比例为1/2的框架中节点的低周反复载荷试验,对不同轴压比和体积配箍率下梁柱节点的受力特点、裂缝开展形式、滞回特性进行了研究。结果表明,超高韧性水泥基材料能明显改善节点核心区的抗裂性能和剪切延性,具有更好的耗能能力,可部分或全部替代节点处箍筋的抗剪作用,具有良好的经济效益。 |

| Abstract: | To study the mechanical characteristics and the seismic behaviors of new beam-column joints by using the cementitious composites with ultrahigh toughness, the cyclic loading tests were carried out on six 1/2-scale inte-rior joints. The study was focused on mechanical character, crack development and hysteretic behavior of the joints under different axial loads and different volume reinforcement ratios. The results show that the cementitious compos-ites with ultrahigh toughness have better energy dissipation capacity, higher crack resistance and shear ductility of joints. It can substitute or partially substitute for the shear stirrups and thus bring good economic benefits. |
