Optimization for Overall Stability

Document Type: Proceeding Paper

Part of: Recent Developments in Structural Optimization

Abstract: This paper synthesizes design of trusses for linear stability constraint as an optimization problem where linear stability is defined as a generalized eigenvalue problem and presents a rather fast converging algorithm of the 'allowable stress' type for its solution. The technique proves to be similar to that used for the design of frequency constrained structures and adds yet another perspective to the already popular 'allowable stress' algorithms.
