A gap must be provided between the bottom of the shelf angle and the brick veneer (below the shelf angle). What is the reason for this gap?
What will be an ideal response?
The gap functions as a movement joint and accounts for two factors:
1) Upward expansion of brick veneer (the bricks expand after they have been laid in the wall). 2) Live load deflection of the spandrel beam to which the shelf angle is anchored. This deflection is downward.
