Masonry Veneer Shelf Angle Load Calculator

Estimate the linear load a steel shelf angle must support from the brick veneer resting on it.

Computed in your browser — nothing you enter is uploaded. Figures are presented for United States against IRC 2024, and every formula is cited under regulatory standards below.

Load on shelf angle

5.59 kN/m

Check your inputs

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
383.15 lb/ft

Running these inputs gives 5.59 kN/m as the load on shelf angle. Expect some drift against the real job; the calculation is solid but conditions on site are not. Currently reading for United States under IRC 2024 — pick a different market above and the figures re-cast accordingly.

Add the equipment this sizes

This result is a specification — 5.592 kN/m — not a quantity. Put the thing it sizes into your project: how many, what you call it, and your supplier’s price.

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. Spotted an arithmetic or standards error? Report it to contact@craftquantities.com with your inputs — confirmed fixes become pinned regression tests.

Frequently asked questions

What is a shelf angle?
It's 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.
