Abstract

Aiming at the problem that the mechanical performance of the FRP connector in the prefabricated sandwich thermal insulation wall directly affects the safety of the wall, the shear performance of the designed new connector is studied through on-site shear tests and numerical simulation methods. , the results show that: (1) The stress and deformation law obtained by numerical simulation and the law obtained by experiment have a high unity, and the stress and deformation of connectors in the overall wall panel unit increase with the increase of external load. (2) The design shear bearing capacity of the connector is 36.11 kN when the relative displacement of the inner and outer wall panels is 2 mm, which can be approximately regarded as the bearing capacity of each connector is 9.1 KN. The shear bearing capacity data is close to 10 times the standard value, and the specimen has good shear resistance.
