| Abstract: | 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. |
