PCI Journal article attests to CarbonCast’s composite action
Behavior of precast, prestressed concrete sandwich wall panels reinforced with CFRP shear grid features testing results for six full-scale insulated precast, prestressed concrete sandwich wall panels with carbon fiber grid in PCI Journal, spring 2011 edition.
All panels were subjected to monotonic axial and reverse-cyclic lateral loading to simulate gravity and wind pressure loads. The research demonstrated that appropriate use of carbon fiber reinforced polymer (CFRP) shear grid can provide an effective shear transfer mechanism in precast, prestressed concrete sandwich wall panels. Importantly, the findings confirm nearly 100% composite action can be achieved through use of carbon fiber reinforced polymer (CFRP) grid shear connections when applied between concrete wythes and EPS or XPS foam insulation.
