Abstract
A method for optimum plastic design of plane frames is studied, taking into account the axial force-bending moment interaction plastic behavior. The frame is regarded as a discrete model, formed by rigid elements which are separated by (generalized) plastic hinges. Alternative loading conditions are considered, in addition to the action of the design-dependent self-weight. The optimization problem is solved as a problem of linear programming into which some technological and construction requirements are also introduced. Optimality conditions are also discussed.Keywords
