RELIABILITY OF PORTAL FRAMES WITH INTERACTING STRESS RESULTANTS

In this study an upper bound theorem formulation of a discretized structure with interacting stress resultants is derived, enabling the reliability assessment by concave quadratic minimization within first-order second-moment reliability theory. Two algorithmic procedures to solve this nonconvex program are presented. The proposed technique illustrates that the stochastically dominant modes differ and the resulting probabilities of failure may change considerably, whenever the interaction of bending and axial forces is considered instead of a predominant bending action. The paper describes two alternating subprocedures which consititue the solution method for the optimum design of portal frames with interacting stress resultants.
