Abstract The purpose of this paper is to propose an analytical model for a new type of steel cushion for use in Reinforced Concrete (RC) frames. Theoretically, steel cushions were installed in the RC frame between a beam and chevron-type bracing elements to dissipate a considerable amount of energy during earthquake events. The cyclic shear behaviours of the steel cushions were experimentally determined by performing quasi-static tests. The results of these tests served as the main basis for a simplified hysteretic model that was proposed for the steel cushions. An analytical model was developed for an RC frame that represents low-rise structures. The analytical models of the steel cushions and the RC frame were superimposed. The effectiveness of the steel cushions was numerically assessed by performing a nonlinear static analysis of the frame instrumented with the steel cushion. The results of the numerical analysis indicate that the steel cushions contribute to the energy dissipation and damping properties of the RC frame. The strength of the instrumented frame was significantly higher than the strength of the bare frame. The proposed model is effective and practical for representing the contribution of the steel cushion to the total behaviour of the RC frame.
