Shear Reinforcing Influence of GFRP Shear Connectors in the Concrete Sandwich Wall Panel (CSWP) for Exterior Envelopes of Buildings

Abstract:

This paper summarizes the experimental results of concrete sandwich wall panels (CSWP)specimens under pull-out loading conducted to investigate the effect of insulation type and reinforcing area of shear connector made with glass fiber-reinforced polymer (GFRP) on the shear behavior of CSWP used as exterior cladding walls.In this study, two types of thermal insulations;expanded polystyrene(EPS)and extruded polystyrene with special slots(XPSS) and wave-shaped GFRP shear connectors with different reinforcing area; 6mm x 2mm and 12mm x 2mm were used for CSWP specimens.Test results indicated that the types of insulations and reinforcing area of GFRP shear connectors have a significant effect on the direct shear behavior between concrete wall and insulation. As reinforcing area of GFRP shear connector increase, increase in shear strength of CSWP with EPS insulation is less than CSWP specimens with XPSS insulation due to relatively lower strength of EPS compared to XPSS strength.
