Experimental Design and Preliminary Testing for Skewed Special Moment Frame Prequalification
<p>Special moment frames having specially detailed connections are common in high seismic regions, providing architectural flexibility for passageways and views without brace obstructions. In situations where the building framing layout requires deviation from typical rectangular framing, skew in …

On the Seismic Performance of Skewed Special Moment Frame Reduced Beam Section Connections
<p>Special Moment Frames (SMFs) are frequently used in high seismic areas for architecturally constrained designs, as they provide lateral system stiffness without the use of braces which often obstruct views and architectural features. Reduced beam section (RBS) connections are popular SMF …

Performance Based Analysis of Steel Buildings
… design using the AISC specifications for a steel Special Moment Frame and the lateral loads from ASCE 7-05 resulted in a building that slightly exceeded an Immediate Occupancy performance level for the BSE-1 Hazard Level. In comparison, a design using the AISC specifications for steel Special …

Effect of Viscous Fluid Dampers on Steel Moment Frame Designed for Strength and Hybrid Steel Moment Frame Design
… of added viscous fluid dampers on a nine story special steel moment frame designed for strength in Seattle. At the initial stages of the work, knowing the fact that moment frames are almost always controlled by drift, it was thought that two different moment frames, controlled by strength or …

Effect of Column Axial Load on Skewed SMF RBS Connection Demands
… buildings in high seismic areas often require special structural systems to transfer large lateral forces induced by earthquake accelerations. The selection of an appropriate seismic steel system (braced frame, moment frame, shear wall, etc.) is often influenced by architectural considerations. …

Evaluating the Fracture Potential of Steel Moment Connections with Defects and Repairs
Steel moment frames are a popular seismic-force resisting system, but it is believed that they are susceptible to early fracture if there is a stress concentration in the plastic hinge region, also known as the protected zone. If a defect is present in this area, it may be repaired by grinding …
