The Design Method and Detailed Requirements of Bearing Capacity of Aluminum Alloy Gusset Joint

Abstract:

According to the theoretical study on the load bearing capacity of aluminum alloy gusset joint, formulae to estimate the block shear rapture load and the local buckling load of plate are proposed. Based on the experimental program, numerical model is established to simulate this joint by means of program ABAQUS. Experimental results agree well with numerical results. Test results and statistic regression technology are used to estimate the value of the coefficients in the proposed formulae. Comparisons between theoretical results and experimental results are conducted to indicate the applicability of proposed formulae. At last, detailing requirements of the joint plate are proposed, and the rationality of detailing requirements is demonstrated through experimental results.
