Standard Practice for Design and Performance of Laminated Glass Subject to Hydrostatic Loads

Importancia y uso:

4.1 Glass is a brittle material with different time dependent properties than other building materials used in the construction of pools. Therefore, the properties of glass are important considerations in the design and construction of glass pools and aquariums.

4.2 Post-breakage glass retention and strength shall be considered in the design of a glass pool or aquarium as a means of maintaining the integrity of the system, deterring cutting/piercing injuries, or fall-through or fallout of the glass.

4.3 The structural design shall be confirmed by calculations by a design professional in accordance with Section 6.

4.4 If testing is required (see 4.4.1 – 4.4.3) to verify post-breakage behavior of the glass, the testing shall be in accordance with Section 7.

4.4.1 For laminates with two glass plies, verification testing is required.

4.4.2 For laminates with more than two glass plies, verification testing is not required if calculations completed in accordance with 4.3 demonstrate that the glass assembly has sufficient strength to sustain the full design load with any one glass ply broken.

4.4.3 When verifying post-breakage behavior by calculation, allowable glass stress for permanent load duration in accordance with Table 1 shall be used for all load cases greater than 1 month.

4.5 The manufacturer of glass pools and aquarium systems shall provide installation directions and fabrication and installation tolerances of their systems.

4.6 Structural Support System—Deflection: 

4.6.1 The glass and support system shall be sufficiently stiff to limit the deflection of the supported glass under the design load to no more than L/240 or 13 mm [0.5 in.] whichever is less, where L is the longest unsupported span for three or fewer side supported systems, or the longest supported length for four side supported systems.
