Abstract
This study investigated the structural performance of precast concrete insulated sandwich panels with cruciform cross section glass fiber-reinforced polymer (GFRP) connectors, based on tensile and shear tests. 5 tensile specimens and 4 shear specimens were fabricated and tested. The load-displacement relation and failure mode of the specimens were analyzed. The results revealed that the average ultimate tension load of the tested specimens with single GFRP connector was 13.14kN with concrete splitting or concrete partial cone failure. For the shear specimens, the average ultimate shear load was 14.83kN with rupture failure of GFRP connector. Furthermore, durability of sandwich panels was investigated, by fabricating and testing 48 tensile specimens with GFRP connectors immersed in tension load had sufficient safety in different design situations.
Highlights
Precast concrete insulated sandwich panels, consist of two concrete wythes and a layer of insulation in between, are widely used as load-bearing cladding in commercial and residential structures nowadays [1]
Studies had been conducted to evaluate the structural performance of glass fiber-reinforced polymer (GFRP) connectors, including tensile, shear and flexural behavior of concrete sandwich panels with GFRP connectors [5,6,7,8,9]

Summary
Precast concrete insulated sandwich panels, consist of two concrete wythes and a layer of insulation in between, are widely used as load-bearing cladding in commercial and residential structures nowadays [1]. Connectors are crucial components in the concrete sandwich panels, which significantly influence the bearing capacity, stiffness and other properties of the panels [2]. Sleeve anchors and welded-wire truss were typical connectors used in sandwich panels [3]. The glass fiber-reinforced polymer (GFRP) connector is a new option in the recent decades, with the advantages including high tensile strength, less heat conduction and easy application. Studies had been conducted to evaluate the structural performance of GFRP connectors, including tensile, shear and flexural behavior of concrete sandwich panels with GFRP connectors [5,6,7,8,9]. Previous research indicated that concrete sandwich wall panels with GFRP connectors had satisfactory composite behavior
