Title: GFRP Connector and Partially Precast Concrete Sandwich Panel System
Author(s): R. Gastmeyer and R. C. Donahey
Publication: Special Publication

Abstract:A new connector system and a new method for the construction of partially precast concrete sandwich panels are described. The new connectors are constructed using glass fiber reinforced polymer and are used to tie two precast concrete layers together through a layer of rigid extruded polystyrene insulation. In contrast to existing connector systems that incorporate steel lattice girders, the new system effectively eliminates thermal bridges and undesirable forced compatibility strains in the concrete layers. In addition to providing energy savings for the building owner, the new system and method can provide cost savings for the wall fabricator.
