A contribution to analytical and numerical tools is presented that permits determinist evaluation of structures' behavior under multiparameter and/or cyclic mechanical, thermal and chemical loads. Particular structure elements undergo plastic and corrosive degrada-tion and dissipate energy, which consists of irreversible contributions, like the work of inelastic strains. The construction and its units' lifetime are estimated according to the dissipated energy criterion. Modeling a numerical implementation of degradation effects are discussed, including cyclic plasticity genera by mechanical and thermal loads, stress corrosion, electrochemical corrosion and low-cyclic corrosion
