1
See Section 3.2.2 for additional CMU, mortar and grout requirements.
2
No more than one fastener may be installed in an individual masonry unit cell.
3
See Figure 18 for the applicable placement zone.
4
Shear can be applied in any direction.
5
Applies to installation in horizontal bed joint with shear load applied parallel to the bed joint. Fastener spacing must be a minimum of 4 inches.
6
Shear direction can be horizontal or vertical (bed joint or head joint) along the CMU wall plane.
7
Applies to installation in horizontal bed joint with shear load applied perpendicular to the bed joint. Fastener spacing must be a minimum of 4 inches.
8
Fastener located in center of grouted cell, installed vertically.
9
Fasteners must be installed a minimum of 8 inches from the end of the wall. Unless otherwise noted, multiple fasteners in a bed joint must be spaced a minimum of
8 inches.
10
Allowable load values apply to fasteners with black or white collated strip or guidance washer.
11
The fasteners listed in the table above may be used for static load conditions and for the seismic load conditions described in Item 1 of Section 4.1.5.
