Abstract：To solve the problem that the safety of precast sandwich insulation wall was influenced by the mechanical behavior of FRP connector, the model from a practical project in Shanghai was used as re-ference. The tests of three pull-out specimens and six shear specimens were used to investigate the pro-perties of FRP connectors of pull-out capacity, shear bearing capacity, failure pattern and load-slip curve. The results show that the pull-out capacity of the connector is 23.5 kN. When the connectors are arranged parallel and vertically to the shear load, the shear bearing capacities of the connector are 19.6 kN and 12.6 kN, respectively. The connectors can meet the design requirement in practical project with a great safety margin. The thermal performance of precast sandwich insulation wall was also tested. The results show that heat transfer coefficient of the wall is 0.407 W?(m2?K)-1, and can meet the need of building energy-saving standard.
