Abstract
An analytical approach to predict the behavior of structures subjected to earthquake-type cyclic loadings is presented. The general kinematic hardening model suggested by Mroz is modified so as to also include the translation of the yield surfaces according to Ziegler's and Prager's original kinematic hardening models. Finite element theory is used for spatial discretization and incremental plasticity theory is used to develop the plasticity equations for all the different hardening models. Results obtained for three numerical examples are compared using the three different translation rules. Both proportional and nonproportional loadings are considered. For two examples numerical results obtained are also compared with the available experimental results.
