The existence of structural damage in an engineering structure leads to the modification of vibration modes and global eigenvalues are usually sensitive to the degree of local damage seismic in bolted connections. In this analytical study, a nonlinear time history analysis which takes into account nonlinear modes and frequencies was adopted. According to this approach, the nonlinear modes and frequencies can be determined by an iterative procedure which based on the method of equivalent linearization. However, the damage analysis of seismic response requires the introduction of efficient structural models capable of describing actual behaviour and the application of an adequate algorithm. The paper presents a Fatigue Damage-Based Hysteretic FDBH model to evaluate the seismic performance of steel moment-resisting frames. The FDBH model is an evolutionarydegrading hysteretic model based on the low-cycle fatigue LCF damage index. Hence an algorithm was developed to characterize nonlinear behaviour in structures for the purpose of either damage identification of these structures.
