A hinge model with elastoplastic behaviour

Abstract

An elastoplastic hinge model for transient beam response analysis has been developed. A variety of monotonic curves as well as hystereutic cycles can be constructed. Special models for unstable cycles of constitutive relationships are offered by this model. Practical cases such as impact of a hollow section or cracking of a reinforced concrete beam can be handled. The application to the analysis of the impact of a rectangular hollow section is shown. Good performance is obtained and comparison is made with the use of an explicit impact code.
