Abstract
Structures under severe loads often go to inelastic range and show nonlinear behavior. Proper modeling of restoring force such that the physical properties can be realistically represented is essential in study of performance and safety of structures under natural or man—made hazards. Also, the estimation of the inelastic structural system parameters and their uncertainties should be based on experimental or field evidence of actual structures, therefore requires methods of system identification and regression analysis. Recent developments in the above areas are summarized with emphasis on restoring force hysteresis, degradation, biaxial interaction and capacity against damage. A simple time domain least—square technique for practical evaluation of restoring force parameters is also presented. Numerical examples are given and applications to damage prediction and damage limiting design are mentioned.
