Abstract:In this paper, a precast concrete sandwich panel system with high thermalresistance and optimum structural performance was developed. Fiber-reinforcedpolymer was used to provide the connector in this panel system. Each connector wasprefabricated in a V-shape with both end hooks providing anchorage in the reinforcedconcrete wythes. The developed shear connecting system is described, along with itsperformance and advantages. An experimental investigation of the connecting systemwas conducted. The experimental program included pure-shear testing of push-offspecimens with a variety of wythe connectors, flexure testing of full-scale specimenswith FRP connectors, and testing of FRP material. The developed shear transfer anddegree of composite were evaluated and the observed behavior of the members ispresented. Design criteria are given for use by engineers and others to apply withappropriate engineering judgment.
