Standard Practice for Determining Load Resistance of Glass in Buildings

Standard Practice for Determining Load Resistance of Glass in Buildings
$ 76.00 In stock


1.1 This practice covers a procedure to determine the load resistance of specified glass types, including combinations of glass types used in a sealed insulating glass unit, exposed to a uniform lateral load of short or long duration, for a specified probability of breakage.

1.2 This practice is applicable to common architectural designs only for which the specified design loads are less than or equal to 10 kPa (210 psf).

1.3 This practice can only be applied to monolithic, laminated, or insulating glass of rectangular shape with continuous lateral support of all four edges. This practice assumes that the edges of the glass are simply supported and free to slip in plane.

1.4 This practice is applicable to annealed, heat strengthened, fully tempered, laminated, and insulating glass units as defined in 3.2.4. This practice is not applicable to any form of wired, patterned, etched, sandblasted, or types of glass with surface treatments that reduce the glass strength.

1.5 This practice only addresses the determination of the resistance of glass to uniform lateral loads. The final thickness and type of glass selected also depends upon a variety of other factors (see 5.3).

1.6 Two procedures are presented which allow the approximate center of glass lateral deflection to be calculated (see Appendix X1 and Appendix X2 ). A procedure is also presented to calculate the probability of breakage of any annealed lite or ply (see Appendix X3 ), for short or long duration loads.

1.7 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. For conversion of quantities in various systems of measurements to SI units refer to Practice E380.

1.8 Appendix X4 lists the key variables used in calculating the mandatory type factors in and comments on their conservative values.

1.9 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
