Brick Veneer Anchor Spacing and Count (TMS 402 / IBC 1405)
Anchor count = ceil(area / area-per-anchor) with the 32 in horizontal / 24 in vertical spacing caps.
Example
You enter
- Veneer wall area (ft²) 200
- Max area per anchor (ft²; 2.67, 2.0 high-demand) 2.67
- Max horizontal spacing (in) 32
- Max vertical spacing (in) 24
You get
- Anchors required 75
Details, formula, and sources
Anchor count = ceil(area / area-per-anchor) with the 32 in horizontal / 24 in vertical spacing caps, per TMS 402 / IBC 1405. A 200 ft^2 veneer at 2.67 ft^2/anchor -> 75 ties; a high-wind 2.0 ft^2 limit -> 100. TMS 402 / IBC and the engineer of record govern.
anchors = ceil(area / area_per_anchor); area_per = 2.67 ft^2 typical (2.0 high-demand); max 32 in horizontal, 24 in vertical spacing.
TMS 402 (Building Code Requirements for Masonry Structures) and IBC 1405 veneer-anchor provisions, by name.
The veneer-anchor area and spacing limits are in TMS 402 and IBC Chapter 14 (many jurisdictions post the adopted IBC). TMS 402 / IBC and the engineer of record govern.
Estimate. AHJ and licensed professional govern.
