The height of brick veneer resting on this shelf angle before the next angle below.

Typically one floor-to-floor height in a multi-story building with shelf angles at each floor line.

The nominal thickness of the brick veneer.

Standard brick veneer with an air space is commonly about 3.5-4 in (90-100mm) thick.

The density of the brick material.

1,900 kg/m³ is a reasonable estimate for standard clay brick veneer.

Load on shelf angle

396 lbf/ft

Medium confidence

This is the veneer dead load only — the shelf angle and its anchor bolts must also be checked for the angle's own weight, any eccentricity from the veneer's offset from the angle's support point, and deflection limits, all outside this calculator's scope.

Equivalent in lb/ft
395.51 lb/ft

What this calculation does not cover

  • This is the weight of the veneer only. The shelf angle's own weight, its anchors and flashing, and anything else bearing on the same run — a lintel over an opening, a sill course, a parapet or coping — are not in the figure. Where an opening interrupts the wall, the tributary height above the angle is not simply the floor-to-floor height either.
  • It is a service load, not a design. Nothing here sizes the angle, its anchor bolts or the connection back to the frame, applies a load factor, or accounts for the moment and torsion from the veneer bearing outboard of the angle's support point, or for the angle's deflection limit. Those are engineering checks and this number is only the starting input to them.
  • The veneer is modelled as a solid wythe at one bulk density. Enter the thickness of the brick alone — not brick plus air space, sheathing or insulation — and expect the real weight to move with coring, mortar joint size and how saturated the brickwork is.
  • The density field stops at 2,400 kg/m³ (about 150 pcf), which covers clay and concrete brick. Dense natural stone veneer sits above that ceiling — granite and marble run roughly 2,600-2,750 kg/m³ — and a density typed above the maximum is capped back to it, so the load comes back low.
  • None of the lateral side is covered: wind and seismic pressure on the veneer, the tie spacing that carries it back to the backup wall, and the soft compressible joint that must sit under the angle so the veneer below is not loaded are all separate calculations.

How to calculate masonry veneer shelf angle load in 4 steps

  1. Supported Veneer HeightThe height of brick veneer resting on this shelf angle before the next angle below.
  2. Veneer ThicknessThe nominal thickness of the brick veneer.
  3. Brick DensityThe density of the brick material.
  4. Load on shelf angleThe tool computes the load on shelf angle from those figures and shows the formula, its sources, and a confidence rating alongside it.

Frequently asked questions

What is a shelf angle?
A steel angle bolted to the building's structural frame at each floor line (or other interval) to support the weight of the brick veneer above it. Without shelf angles, tall veneer walls would need to bear all the way down to the foundation, which isn't practical for multi-story buildings.
Why does veneer need periodic vertical support at all?
Brick veneer is a non-structural (cladding) element with limited height it can safely span without additional support — shelf angles break the veneer into shorter, independently-supported segments at each floor.
Does this include the expansion joint gap below each shelf angle?
No — a soft (compressible) horizontal joint is typically left below each shelf angle to accommodate building movement without transferring load to the veneer below; that gap sizing is a separate calculation.
Preliminary estimate, not certified engineering. This tool produces an indicative quantity calculation for planning purposes only — it is not a certified structural analysis, a guaranteed material takeoff, or a substitute for building department approval. Always verify measurements on-site and have a licensed contractor or structural engineer review any load-bearing, code-sensitive, or safety-critical work before purchasing materials or starting construction.
