Precast Concrete Corbels for Insulated Wall Panels
Insulated panels can thus provide a weight savings of 40% over solid panels, and an insulation rating of nearly R-21 (thermal resistance of 21 h.ft2.°F/Btu or 3.7 m2.K/W). Because these panels are also air and moisture barriers and can provide both the exterior and interior finishes for a building-all in one product-they are very competitive with alternative cladding systems. Wall panels often require corbels to support roof and floor joists. Because corbels are very short cantilevers, they are subject to special loading and design criteria as given by Chapter 16 of the ACI 318-14 Building Code1 and Section 5.9.4 of the seventh edition of the PCI Design Handbook.2 The shear-flexure and shear-friction approaches are used to ensure that reinforcement crosses the nearly vertical cracks that are expected to develop at the interface between the corbel and the wall as the load approaches the corbel's ultimate capacity.
