Abstract : Conventional minimum weight structural design methods generally assume that a continuous spectra of shapes are available; however, actual sections consist of a finite set of discrete sizes. By utilizing discrete programming techniques, it is possible to develop design methods which work directly with the properties of the available sections. A design approach based on the static theorem of plastic analysis is formulated herein. The resulting optimization problem is a mixed integer type. Alternatively, a pure integer linear optimization problem results when the kinematic theorem is used to formulate the problem.
