ABSTRACT
This paper comments the behaviour of structural steel elements under cyclic load based on the ECCS [ 1* recommended testing procedure. Some experimental studies and numerical models on the cyclic behaviour of steel subassemblages are presented. A numerical model for damage accumulation and for predicting the failure of structural subassemblages under cyclic loading is also presented. This model is expressed as a function of the inelastic strain and the dissipated hysteretic energy. It is shown that failure of the structural element does not depend on the loading histories but depends on the accumulation of the inelastic strain.
