N2 - Recent earthquakes have shown the brittleness of steel moment frames (SMF) with weld connections. Moment-resisting steel constructions are damaged in earthquake-prone areas. According to study, cracking of the weld between the beam flange and column face and excessive loads in this region cause severe damage. For panel zone stress reduction, a Reduced Beam Section (RBS) connection may be beneficial. In this paper, three-dimensional finite element analyses are used to study the seismic performance of RBS beam–column connections with radius cut, straight cut, tapered cut, and drilled flanges-cut geometries (RBS-RC, RBS-SC, RBS-TC, and RBS-DF in the model) under cyclic loading. Results showed that the radius-cut cutting geometry increased the energy absorption capacity and ductility. It also implies the highest dissipates energy efficiently.
