| Abstract: | On the basis of the short-cycle loading test of the four knots strengthened by the dimensional angle-iron framework, this paper deals with the crack way,shear deformation and rotation of the knots. The effect of the dimensional angle-iron framework on the crack way in essence is found out, the method to calculate the crack shear force is brought forward,and the theoretical results are compared with the measured results. The effect of the dimensional angle-iron framework on the shear-force behavior of the knot is analyzed. The formula to calculate the shear-force capability of such knots is presented. |
