摘要
A certain strength is required for the window glasses in tall buildings due to the high wind pressure. The strength for large size glasses is generally deduced from the testing results of specimens with samll sizes by the Weibull statistics theory. By a great deal of experiments the authors have studied the thickness , span and width effects of flat glasses of on bending strength under biaxial stresses. Compared with the Weibull theory, the accuracy of strength is determined and a modification is made for the volume effect proposed by Weibull. The size effect of Weibull modulus is investigated as well and the reasonable specification for flat glass strength is suggested.
