Besides, extension of the formula is considered for the joint which has stepped column with large depth simplifying a pile cap based on experimental data. The formula of raking-out failure strength in previous papers is a linear combination force of concrete and hoops: the force of concrete in the assuming fracture at an angle of 45° and the force of hoops across the assuming fracture. This formula gave roughly good calculation results only for the specimens without stepped column, while the calculation values of those with stepped column were about 8 percent lower than the experimental values on average. Then we changed the formula and as a consequence, modified formula provided estimated strength as precisely as the current formula for the straightcolumn specimens, but as to the stepped-column specimens, the estimated strengths by the modified formula were a little lower than the experimental results. However, the proposed formula can take account of the different substitution of shear reinforcement depending on their distance from beam bars.
