Use of the annealed or heat strengthened glass plies will also reduce the amount of load transferred into the structure. Laminated glass fabricated with fully tempered glass plies has a tendency to leave the supporting glazing system frame after fracture whereas laminated glass fabricated with annealed or heat strengthened glass plies will remain in the frame and absorb remaining load through tensile membrane behavior.

Work Item s – proposed revisions of this standard. The system shall be designed to ensure that the glazing fails prior to the framing system that supports the glazing and its attachment to the structural framing system.

The width of silicone or glazing tape is referred to as bite and is shown and discussed in Guide C The fasteners that attach the framing system that supports the glazing to the structural framing system shall be designed to resist a uniform load acting on asgm blast resistant glazing that has a magnitude of at least: The fasteners that attach the framing system that supports the glazing to the structural framing system shall be designed to resist a uniform load acting on the blast resistant glazing that has a magnitude of at least:.

ASTM F2248 – 12

Blast testing has shown that use of fully tempered glass plies, when fractured during a blast event, have poorer post blast performance than annealled or heat strengthened glass plies.
