This invention provides a method for calculating the out-of-plane bearing capacity of unequal-sided angle steel cross-bracing members. An external load is applied to the angle steel, and the resulting compression member is discretized into several micro-segments. The curvature of each micro-segment is calculated, and the internal forces of the micro-segment sections are further calculated. This calculation is iteratively performed until the internal forces and the applied external load satisfy the convergence tolerance. Based on the external load and the matching micro-segment curvature, element stress, and micro-segment section internal forces, the bending moment of the section is obtained by integration. The length and rotation of each micro-segment are then calculated using the moment increment formula and the micro-segment rotation formula, respectively. This iterative calculation continues until the micro-segment rotation is zero. The lengths of each micro-segment are then summed to obtain the member length corresponding to the given external load. This method employs a reverse calculation approach, determining the corresponding bending moment based on the member's buckling shape, and then obtaining the member length, thus filling the gap in the calculation of the out-of-plane bearing capacity of unequal-sided angle steel.
