The check criteria for the fillet weld strength of the primary supporting members are obtained according to the design method of the fillet weld in steel structure. The weld stresses of the primary supporting members are calculated for a single hull bulk carrier by the finite element method (FEM) and the calculation model method. The results show that the weld factor in CSR-BC rule could meet the strength requirements, and the two algorithms are similar in the calculated weld stress. It can verify the safety of the weld leg height in CSR-BC rule and provide references for the optimization of the weld factor specification.
