Thin-chamber insulating glazing (TC-IG) possesses a typical double cavity structure, and the influencing factors of its load-bearing deformation performance are more complex. Moreover, the deformation and strength of middle glass also exhibits the significant thickness effects. In this paper, ABAQUS finite element analysis software was used to build a solid modeling of TC-IG, and the effects of glass thickness and wind load on the displacement, maximum principal stress and load distribution ratio of TC-IG under wind load are studied. The results show that the maximum displacement of each piece glass of TC-IG locates at the center of the plate and decreases uniformly around the glass under wind load. With the thickness of middle glass decreases, the maximum displacements of the outer and inner glasses increase, and the maximum displacement of the middle glass first increases and then decreases. The maximum principal stress of the middle glass is lower than that of the outer and inner glasses. With the thickness of the middle glass decreases, the maximum principal stress of the outer and inner glasses increases, while the maximum principal stress of the middle glass decreases. With the wind load increase, the maximum principal stress of the middle glass is shifted from the center of the plate and nearby positions to the four corner positions. The thinner the thickness of the middle glass is, the closer the maximum value of the maximum principal stress is to the four corner positions, which may become the starting point of fracture of the middle glass under high wind load. The wind load distribution ratio of each piece glass of TC-IG is mainly related to the thickness of the middle glass. When the thickness of the outer and inner glass is constant, the thinner the thickness of the middle glass is, the lower the load distribution ratio is, and the outer and inner glass become the main part of the wind load.
