Summary:The elastomeric bearing pads playing an important role by transforming the loads from bridge superstructure to its substructure. The fatigue life estimation of these elements is necessary to avoid any problems resulting from deterioration of such elements. To do so, the current study is devoted to develop a three-dimensional model for steel-laminated bearing pad subjected to different designated applied loads. The Ogden model, one of the built-in constitutive models in ABAQUS software, was used to fit the experimental load-deformation curve and to obtain the coefficients of the rubber material used in the pad to feed the ABAQUS software. The pad was modelled with elements C3D8R, C3D8RH, and M3D4R to represent the steel, rubber, and rubber skin respectively. Four loads with three frequencies for each load were selected to applied on modelled pad. Fe-safe, one of ABAQUS software package, was used to find the fatigue life for modelled pad. The results showed a good agreement with previous experimental studies on this field.
