Steel shear fuses, can prevent the transfer of damage to the main structural components. However, previous studies have focused solely on the geometry of the shape, and the two parameters of shape geometry and fuse material have not been investigated simultaneously. In this research, in addition to the shape geometry, two other materials with higher energy absorption capacity have been investigated, which resulted in an approximate 131% increase in energy absorption. This research investigates the behavior of steel shear fuses with different materials (SS400 and LY225) as well as geometric parameters including thickness (t), the length of the fuse’s reduced section (wl), and the width of the reduced section (wt). To this end, numerical analyses were performed on the fuse model, and hysteresis, stiffness, and damping curves were extracted for each cycle. The results showed that the shear fuse made with SS400 material performed better than the other materials. Also, among the shape parameters, increasing the thickness of the piece increases the energy absorption of the model, increasing wl decreases stiffness, damping, and energy absorption, and the parameter wt shows better performance in terms of energy absorption within the range of 19.1 to 63.5 mm. Therefore, it can be concluded that the correct selection of materials and the optimization of the geometric dimensions of the shear fuse play a fundamental role in increasing the stability, energy absorption, and seismic performance of this element.
