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 ...
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 ...
Mechanical performance is comparable to other widely used stainless steels, such as 17-4 ph, but nonmagnetic properties are useful for magnetic-sensitive instrumentation such as magnetometers.
