The mathematical model of the braced stress-strain in the vacuum glazing was established with the crunode method by elastic mechanics. The braced stress-strain field of vacuum glazing was received, and the stress-strain distribution was analyzed at the same time. Electric test method was used to validate the stress distribution. The experimental results are shown that the maximal stress of vacuum glazing occurs in the second braced pillar of the four-square side. The maximal stress value by elastic mechanics is 11.057MPa, while the measured value by electric test method is 11.765MPa, and its tolerance is only 6.02%. The positive stress in the cross section of the braced pillar is 179MPa, the longitudinal strains of steel and glazing braced pillar are 0.2686μm and 0.7414μm, respectively. The tolerance of braced pillar height and the glazing level degree are controlled to guarantee force equality, which increases strength, dependability, and service life of vacuum glazing.
