Based on the results of parameter analysis of RHS joints obtained by nonlinear FEM, and the results of studies of references [2] and [3], a model called the equivalent frame tube model which can properly simulate the characteristic of the ultimate strength of RHS joints is proposed to approximately analyze the ultimate web crippling strength of RHS cross or X joints. Finally, a design formula is derived to predict the ultimate strength of RHS cross or X joints. 85 test results are correlated with the authors' formula and a mean value of 1.22 with a very small scatter about it (COV=0.11) is obtained. Comparing with others' formulas, the authors' formula has the advantages of better correlation with test results and simplicity in form. |
