Gustavo J. Parra-Montesinos is coming to the rescue of concrete-frame designers and contractors in earthquake country, long bedeviled by rebar-congested coupling beams that span openings in seismic ...

A recent series of dynamic tests demonstrates that there are several types and doses of steel-fiber reinforcement that can be used in performance-based seismic design of coupling beams—headers that ...

The ACI Foundation is pleased to announce the completion of a new research product: Evaluation of Seismic Behavior of Coupling Beams with Various Types of Steel Fiber Reinforced Concrete. Gustavo J.

Zero-backlash beam couplings have high torsional stiffness and accommodate misalignment. The couplings use two sets of overlapping spiral cuts Beam Couplings (Courtesy of Ruland). Zero-backlash beam ...

Understanding how helical, curved beams operate — how their spiral cuts accommodate angular and parallel misalignment, axial motion, and system vibrations — is the key to knowing how they will perform ...
