Structural optimization using incremental equations and sequential linear programming

This paper discusses the use of the incremental equations of structural mechanics and the technique of sequential linear programming as a general solver for structural optimization problems. The use of the incremental equations simplifies the formation of the problem, while sequential linear programming provides a trusted tool for its solution. Examples from design for allowable stress, specified displacements, buckling, and optimal shape are included. It is concluded that these methods comprise a simple tool for use by the structural engineer.
