Brick Wall Load Capacity Calculator
Allowable line load on a masonry wall with slenderness reduction (IS 1905 style).
A 230 brick wall in decent mortar carries ~100 kN/m allowable — fine for two storeys of load-bearing construction, which is exactly how pre-RC India built everything.
Formula
Note: Simplified k_s; eccentric loads and openings need the full code treatment.
Brick Wall Load Capacity Calculator is a free brick wall capacity for structural engineers, fabricators and site engineers — instant, accurate and 100% client-side, with the governing formula and reference shown next to the result so the number can be defended, not just quoted.
About Brick Wall Load Capacity Calculator
Allowable line load on a masonry wall with slenderness reduction (IS 1905 style). The calculation implements P = f_b·k_s·t (k_s from slenderness 0.75h/t) (IS 1905 — structural masonry). A 230 brick wall in decent mortar carries ~100 kN/m allowable — fine for two storeys of load-bearing construction, which is exactly how pre-RC India built everything.

Frequently asked questions
What formula does the Brick Wall Load Capacity Calculator use?+
It computes P = f_b·k_s·t (k_s from slenderness 0.75h/t), per IS 1905 — structural masonry. The formula is displayed under the result.
What should I keep in mind when using this calculator?+
A 230 brick wall in decent mortar carries ~100 kN/m allowable — fine for two storeys of load-bearing construction, which is exactly how pre-RC India built everything. Note: Simplified k_s; eccentric loads and openings need the full code treatment.
Can I use this for real structural design?+
It implements the exact textbook/code formula cited below the result and is ideal for sizing, checking and learning. Final designs should be verified by a qualified engineer against the full code with all load cases.
Is the Brick Wall Load Capacity Calculator free to use?+
Yes — completely free, no sign-up, no limits. It runs client-side in your browser, so inputs stay private and results are instant even on slow connections.
