This practice assumes that 1 s1300 supported glass edges for two, three, and four-sided support conditions are simply supported and free to slip in plane; 2 glass supported on two sides acts as a simply supported beam; and 3 glass supported on one side acts as a cantilever.
Interlayer samples shall experience full laminating thermal history prior to measurement. Similarly the LS factor for Lite No. No items in cart.
The actual thickness of the glass is 5. These minimum glass thicknesses are presented in Table 4. These effective thickness values can be used with standard engineering formulae or finite element methods for calculating both deflection and glass stress of laminates subjected to load. The specified design load shall be used for this calculation. If the charts are used to predict the strength of freshly manufactured glass, the results may be conservative.
The greater the shear resistances, the more effectively the two glass plies couple and resist deformation under loading.

For a single monolithic lite with two surfaces equally at risk, p 5 1.
Significance and Use 5. Determine if the skylight will support a 6. Complete discussions of the formulation of the model are presented elsewhere 2, 3. Therefore the LR of the IG is: Use the following equation to calculate the equivalent 3-s duration design load: E Terminology of Building Constructions.
ASTM E – 12ae1 Standard Practice for Determining Load Resistance of Glass in Buildings
The model allows the probability of breakage of any lite or ply to be specified in terms of two surface flaw parameters, m and k. Read more about subscriptions.
We need your help! Convert kPa to inch-pound units by multiplying 2.
The outboard lite Lite No. This practice shall not apply to other applications including, but not limited to, balustrades, glass floor panels, aquariums, structural glass members, and glass shelves. Copyright Compu-tecture, Inc. The selection of the surface flaw parameters was based upon the best available data and engineering judgment. A larger combined dimension may result in excessive sealant stress and glass stresses due to temperature and altitude conditions.
The specified design load shall be used for this calculation. Register for a trial account. Subscription – always available and updated A web subscription provides an easy and secure access to standards, and you are guaranteed to always have the latest edition. The lower charts of Fig. For insulating glass units, this practice only applies to insulating glass units with four-sided edge support. Therefore the AN lite probability factor becomes: Such deflections, which will exceed the lite thickness, should be rounded to the nearest mm 0.
