Abstract: In order to study the bearing capacity of double-curvature cold-formed single glass, cold forming and loading tests of 8 single tempered glass plates supported by two long frames were carried out, the distribution law of internal stress in glass plate during cold forming was analyzed, the bearing capacity of cold bending glass under the coupling effect of cold-formed stress and negative load was studied through the ultimate bearing capacity test. The test results showed that the maximum cold-formed principal tensile stress increased linearly with the increase of torsional curvature and appears in the corner area of short side which adjacent to the cold forming corner. The bearing capacity decreased linearly with the increase of distortion rate. And the position of maximum stress after the coupling changed with the increase of load. Conclusion could be made that in the design of cold-formed glass, the key of bearing capacity design was to find the maximum point of cold-formed stress and the maximum point of cold-formed coupling stress, the thickness of glass plate should be designed according to the coupling of cold forming rate and external load.
