چکیده
A direct computational method is presented for the evaluation of the robustness function of linear elastic trusses associated with stress constraints. Under the uncertainties of external forces based on the info-gap model, the robustness function is formulated as the optimal objective value of an optimization problem with infinitely many constraint conditions. By using the strong duality theory of the second-order cone programming problem, we reformulate the present problem to a numerically tractable form without any variable. The robustness functions are computed for various trusses under several uncertain loading circumstances.
