Primal-dual Formulation Research Articles

A primal-dual method for minimum weight design of statically determinate structures with several systems of load

The problem of finding the minimum weight configuration for a statically determinate structure of fixed layout under two alternative load systems, as analysed by Chern and Prager, is re-examined by a special primal-dual formulation known as geometric programming. It is found that geometric programming in its unmodified form is less general than the Chern-Prager primal-dual method but does offer certain advantages with respect to information content at the optimum.
