Hysteretic Models for Cyclic Behavior of Deteriorating Inelastic Structures

摘要

Two hysteretic models (a polygonal model and a smooth model) for inelastic211u001ebehavior of macro-models of structural components are developed. These models can 211u001esimulate the deteriorating behavior of strength, stiffness, and bond slip. The 211u001etheoretical background, the development and the implementation of these models 211u001eare presented. The report shows a holistic picture of the modeling of one-211u001edimensional inelastic material behavior and indicates how various hysteretic 211u001emodels are obtained from the basic principles of mechanics and thermodynamics 211u001ethrough numerous assumptions, which lead to certain approximations. Finally, the 211u001eincorporation of the hysteretic models into two computer programs (IDARC2D and 211u001eNSPECTRA) is described. The appendix focuses on the implementation details of the 211u001epolygonal hysteretic model.
