This comprehensive text addresses the elastic and plastic behavior of general structural elements under combined stress. It sets out to examine the stress-strain behaviors of materials under simple test conditions and proceeds to show how these behaviors can be generalized under combined stress. The topic of structural plasticity is presented in a manner that is simple and concise, encompassing the classical theory of metal plasticity as well as concrete plasticity. An unabridged J. Ross Publishing republication of the edition published by Springer-Verlag, New York, 1988, 606pp. Key Features - Outlines the finite element implementation of the generalized stress-strain relations for the solution of practical steel and concrete structural problems - Provides worked examples, end-of-chapter problems, answers to selected problems, and clear illustrations and tables - Includes important constitutive equations for structural materials and applications to steel and concrete structures - Offers examples of the most useful constitutive models and analytical methods
