This paper describes the structural behavior of insulated concrete wall panels with EPS insulation. That panels reinforced with Fiber Reinforced Polymer (FRP) truss shear connector to achieve composite action of inner and outer concrete wythes. Main test variables are FRP cross section, width and picth. According to the test result, the shear capacity of increased due to reinforced with FRP truss shear connector. And width 12, 18 mm shear connector need more than 30 mm experiments about reclamation deep.
