9.20.9.6.(2)

Intent 1:

To limit the probability of discontinuous reinforcement, which could lead to an inadequate resistance to lateral loads or gravity loads imposed by the glass block's own weight, which could lead to cracking at vertically aligned mortar joints.

This is to limit the probability of compromised structural integrity, which could lead to:

• structural failure of masonry construction, or
• where glass block is part of an environmental separator, the excessive deformation, displacement or failure of required environmental separation elements, which could lead to deterioration, which could lead to further compromised structural integrity.

This is to limit the probability of damage to the building.
