 the development of a new replaceable horizontally steel arc-cut damper (HACD) designed as a fuse element in steel-coupling beams for earthquake protection of reinforced concrete shear walls with openings. The HACD is fabricated from a steel arc-cut plate and restraining plates positioned by vertical steel stiffeners. The proposed damper is an in situ, weld-free energy dissipater device, which eliminates the on-site installation difficulties. The seismic induced energy is dissipated through shear yielding of the arc-cut plate when the device is subjected to inelastic cyclic deformation. The optimized shape of HACD with adequate ductility and dissipation energy capacity is obtained using finite-element analysis. The result of numerical analysis under pseudo-dynamic displacements indicates its suitable energy dissipation, stable hysteric response, and remarkable ductility through shear yielding of the arc-cut shear plate. The performance of the numerical approach is justified through the analysis of tested dissipative device available in the literature.
