Regarding the strength of a sheet of flat glass suffering a wind pressure, several studies have been reported and some practical formulas of strength calculation based on experiments have been proposed. However, the deflection and stress of a sheet of flat glass under such condition have not been know compretely. We practised a test and attemped the analysis of the results, aiming to clarify the above points and to obtain a more reasonable formula to calculate the strength and deflection of a sheet of flat glass under a wind pressure. The fracture tests were performed by an air pressure on sheet glass of 3, 5 and 6 millimeter thickness for the size of 1 meter, as well as polished plate glass of 5, 6, 8, 10, 12 and 15 millimeter thickness for the sizes of 1 meter square and 2 meter square for each of the thickness. In this paper, we discussed the relation between the load and the deflection as the load and the strain for a square sheet of flat glass, on the basis of the test results. According to the test results, the behavior of a sheet of flat glass can, when it suffers a load, be explained by assuming that not only a bending force but also a membrane force is effective.
