Taking into account the modern requirements for buildings and constructions the glass should be considered not only as a light transmissible protecting material, but as an architectural material for mechanical load. In designing the light transmissible constructions the glass thickness is made instinctively, as a rule, and in checking calculation the understated calculated strength is used.

To determine the real strength properties we conducted the experiment of flat glass of the main Russian and some foreign manufacturers. The values of internal glass tensions were defined before the experiment.

Some results of experimental research and comparison of the given values with theoretical coefficients are presented. As a result of experiments we concluded that in theoretical research the flat glass used in construction should be considered as a flexible plate supported in four sides with partial jamming, and thus the maximum tension in cross bending appears in the angles of such plates.
