Optimization of plane frames by modification of fully stressed design method

In statically indeterminate frame structures, the load carried by each member is not only a function of the applied load, but in general a highly non-linear function of the relative cross-sectional properties of the members. Since the feasible region is non-convex, it is possible to have more than one local minimum each corresponding to a load-carrying mode. Each local minimum represents the optimal design for a particular mode of behavior of the structure which is a design with an efficient distribution of the material in the structure. The local minimum that represents an optimal design for a particular mode of behavior in a structure can be fully-stressed or non-fully-stressed, indicating that the design does not have to be fully-stressed to be optimal. However, the fully-stressed design method converges to the optimal design for a particular mode of behavior only when it is fully-stressed.
