Weld type between parts will make a difference on structural performance, which is especially important for a daouble-walled shell. To get clear this problem, numerical simulation is conducted to investigate the influence of weld plans between frame and out shell on structural stress and stability. Numerical results show that the change of weld plan between frame and out shell is small in case of a 15MPa external pressure, stress of shell is below the critical value, and the ultimate bearing capacity changes a little. Thus, the weld plan of point weld for frame and out shell could be applied while the double-walled shell is under construction.
