摘要:
通过对配置600 MPa级高强钢筋高韧性混凝土框架梁柱中节点进行拟静力试验研究,对比分析高强钢筋高韧性混凝土框架梁柱中节点的破坏特征、节点核心区剪切变形、梁端塑性铰变形及各种变形组成比例等。研究结果表明:配置600 MPa级高强钢筋高韧性混凝土中节点的破坏特征比普通混凝土节点得到显著改善,节点核心区剪切变形得到减小,梁端转动能力得到增加。减小配置600 MPa级高强钢筋高韧性混凝土框架梁柱中节点轴压比或剪压比、增加配箍特征值能够改善节点核心区的剪切变形,提高梁端塑性转角,从而提高配置600 MPa级高强钢筋高韧性混凝土框架梁柱中节点的变形性能。
Abstract:
The beam-column interior joint with 600 MPa reinforcement steel bar and high toughness concrete were tested under low cyclic loading.The results in terms of damage characteristic,shear deformation of joint core area,plastic hinges deformation of beam-end and proportion of all kinds of deformation were compared.It is shown that the damage characteristic of beam-column interior joint with 600 MPa reinforcement steel bar and high toughness concrete were improved compared with interior joint with 600 MPa reinforcement steel bar and normal concrete.The shear deformation of joint core area was also decreased.The plastic hinges deformation of beam-end was increased.With the decrease of shear compression ratio or axial compression ratio and increase of stirrup characteristic value,the shear deformation of joint was improved and plastic hinges deformation of beam-end was increased.Therefore,the deformation behavior of beam-column interior joint with 600 MPa reinforcement steel bar and high toughness concrete can be improved.
