| 摘 要： | 文章通过五榀钢筋混凝土梁柱偏心节点的试验研究 ,了解了梁端水平加腋的节点在低周反复荷载作用下的裂缝分布、钢筋应变发展和荷载变形性能 ,证明了梁端水平加腋可以显著改善偏心梁柱节点的抗震性能 ,在加腋区配置适量的斜向钢筋能够充分发挥加腋的作用。另外 ,对于加腋区的斜向钢筋数量提出了建议。

| Abstract: | Experimental study of five reinforced concrete eccentric beam column joints are reported in this paper.The crack pattern, the strains in inclined and longitudinal beam reinforcement and the load displacement hysteresis loops were got of beams of one ordinary eccentric joints and four eccentric joints connecting spread ended beams, which were tested under cyclic reversed loading. Experimental results indicated that the seismic behavior of eccentric beam column joints connecting spread ended beams is fairly better than that of ordinary eccentric beam column joints, and enough inclined beam reinforcement is needed for the eccentric joints connecting spread ended beams. The suitable amount of inclined beam reinforcement is also proposed. |
