摘　　要：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 。Based on the experimental results of two interior wide flat beam\|column joints under low cyclic loading, the paper analyzed destroyed process and destroyed patterns of flat beam\|column joints, and verifies that the SFRC flat beam\|column joints show higher strength, stiffness, ductility, energy dissipation and lower strain of steel. The formula of ultimate shear resistance of SFRC flat beam\|column joints and condition of confined section were also presented, and the calculated results come from these formula are identical with the test results.
