This work proposes a damage constitutive model at composite constituent level that accounts formonotonic failure and fatigue effects by affecting both the strength and the stiffness of the compositecomponent, steel or concrete. The behaviour of the composite material will be obtained by means ofthe serial/parallel rules of mixtures (SP ROM) theory [1]. The constitutive model is based on thedamage model proposed by Oliver et al. [2] and used in Oller et al. [3]. Its capabilities of dealing with?High Cycle Fatigue? in steel have been studied by Barbu et al. [4] and offered good results in termsof life prediction
