Abstract
There is a great demand to improve both the structural and thermal characteristics of insulated precast concrete sandwich panels. This paper addresses the potential of using a number of Glass Fibre Reinforced Polymer (GFRP) connectors developed in this research program as an alternative to metallic connectors. The objective is to reduce thermal bridging in the sandwich panels, while transferring shear forces to develop composite action within the panel. The panel incorporates a new system of concrete wythes and studs connected by the GFRP connectors, where the studs are not in direct contact with the wythes. The load-slip response of the system has been established through shear tests. It was also shown that adhesion between the insulating foam and concrete provides significant shear resistance prior to engaging the GFRP connectors.
