An Unstiffened Eight-Bolt Extended End-Plate Moment Connection for Special and Intermediate Moment Frames

Morrison, M. L., Schweizer, D. Q., Quayyum, S., & Hassan, T. (2019, April 29). Journal of Structural Engineering.

By: M. Morrison n, D. Schweizer*, S. Quayyum* & T. Hassan n

topics (OpenAlex): Structural Load-Bearing Analysis; Fatigue and fracture mechanics; Mechanical stress and fatigue analysis
TL;DR: Bolted extended end-plate (BEEP) moment-resisting connections are prequalified for use in special and intermediate moment frames and the current limits of this prequalification dictate that these connections cannot be used in special moment frames. (via Semantic Scholar)

2016 article

Seismic Enhancement of Welded Unreinforced Flange-Bolted Web Steel Moment Connections

Morrison, M. L., Schweizer, D. Q., & Hassan, T. (2016, June 6). Journal of Structural Engineering.

By: M. Morrison*, D. Schweizer* & T. Hassan n

author keywords: Steel moment connection; Seismic performance enhancement; Beam plastic hinge; Heat-treated beam section; Reduced beam section; Modified WUF-B; Metal and composite structures
topics (OpenAlex): Structural Load-Bearing Analysis; Mechanical stress and fatigue analysis; Metal Forming Simulation Techniques
TL;DR: Detailed finite element (FE) analysis of post-Northridge WUF-B connections is presented to better understand the mechanisms which limited connection ductility in laboratory tests and provides the benefit of reduced field welding and UT inspection without sacrificingconnection ductility and seismic performance.
