Uniaxial Mass-rig Specs

The uniaxial mass-rig consists of a moment frame in the out-of-plane (relative to experiment) and a sway frame in the testing plane. The mass-rig provides 20 kips (89 kN) of laterial effective weight to which an additional 120 kips (533 kN) may be added. The frame allows approximately ±15 inches (±381 mm) of displacement before the cable restrainers are engaged.
