根据宽扁梁柱节点在低周反复荷载作用下的试验 ,分析了宽扁梁柱节点的破坏过程和破坏类型 ,研究了在宽扁梁柱节点内掺入钢纤维后 ,其强度、刚度、延性和耗能能力的提高及钢筋应变的降低 ;提出了钢纤维混凝土扁梁柱节点极限抗剪承载力的建议设计公式和截面限制条件 ,其计算结果与试验结果吻合较好
According to the test of wide flat beam-column joints subjected to low cyclic loading, the failure process and failure types of wide flat beam-column joints were analyzed. The effects of strength, stiffness, Ductility and energy dissipation capacity and reduction of steel strain. Proposed design formulas and cross-section constraints for the ultimate shear strength of steel fiber reinforced concrete beam-column joints are proposed. The calculated results are in good agreement with the experimental results
