On the Seismic Performance of Skewed Special Moment Frame Reduced Beam Section Connections
… often obstruct views and architectural features. Reduced beam section (RBS) connections are popular SMF connection details developed following the Northridge earthquake to limit brittle fractures within connection welds. Current American Institute of Steel Construction (ASIC) provisions (i.e. AISC …

LOCATION AND CONFIGURATION OF REDUCED BEAM SECTION CONNECTION EFFECTS ON STRENGTH, STIFFNESS AND DUCTILITY OF MOMENT STEEL FRAMES
… the pre-Northridge moment frame connections. Reduced beam section (RBS) connection is one of the most widely used connections after the Northridge Earthquake. Instead of increasing the steel at beam-column, the RBS connection rather removed steel from the flange of the beam. This connection …

Experimental Design and Preliminary Testing for Skewed Special Moment Frame Prequalification
… design methods can accommodate skew at the beam-to- column connections. To investigate the effect of out-of-plane skew on the performance of reduced beam section special moment frame connections, an experimental test is designed and a preliminary prequalification test is performed. This …

Multi-hazard performance of steel moment frame buildings with collapse prevention systems in the central and eastern United States
… resistance, or ductile moment frames with reduced beam section connections designed for moderate seismic demands. The research shows that collapse prevention systems were effective at reducing the conditional probability of seismic collapse during Maximum Considered Earthquake (MCE) level …

Evaluating the Fracture Potential of Steel Moment Connections with Defects and Repairs
… cyclic bend tests. To do this, six full-scale reduced beam section (RBS) connections were tested having arrays of repairs or defects applied to the flanges. The repairs were 0.125 in. deep notches ground to a smooth taper and 0.25 in. deep notches ground to a smooth taper, welded, and ground …

Effect of Column Axial Load on Skewed SMF RBS Connection Demands
… that limit the use of non-orthogonal (skewed) beam-column connection geometries. A recent study has investigated laterally skewed moment frame connections, indicating that skew increases the potential for column twist and column flange yielding; however, it is unclear how realistic column axial …
