CIII-2 UHPFRC Space-Frame Column under Symmetric Cyclic Loading (ACI 374)

A column made with ultra high performance fiber reinforced concrete (UHPFRC) with a square cross section of 28" x 28" and a clear height of 8'-10" was subjected to an axial load equal to 30% of the gross concrete compression capacity followed by a symmetric cyclic displacement reversals until the lateral resistance of the specimen degraded to 20% or less of the peak resistance exhibited during the test. The test was conducted at the Multi-Axial Subassemblage Testing (MAST) facility at the University of Minnesota-Twin Cities.
