Abstract:In order to study calculation method of bearing capacity of TEMCOR joints in aluminum alloy shell structures, failure modes of 5 TEMCOR joints with different sizes and members under different bending loads were analyzed. Joint bearing capacity of each failure mode was derived. With the help of ABAQUS software, the finite element method was used to simulate the loading process and the coefficient γ of the tension of the gusset plate and the rod caused by stress concentration was given. Comparison with experimental results shows that the simplified calculation formula of bearing capacity of TEMCOR joints in aluminum alloy shell structures has good feasibility, and it sets aside a certain safety margin considering the massive tear brittle failure form in joints, which can be applied to actual engineering design of TEMCOR joints in aluminum alloy shell structures.
Keywords:aluminum alloy shell structure; TEMCOR joint; bearing capacity; design method
