Corbel design

Corbel Design Calculator — Quick & Detailed

Enter geometry, loads, and material properties. Choose Auto θ to use a recommended strut angle (61.5°). You can override with a custom θ if desired.

Breadth (b) mm

Overall depth (d) mm

Distance load line from column face a_c (mm)

Distance from bearing to tension steel d_y (mm)

Bearing plate width (mm)

Bearing plate length (mm) (along span)

Design load F_Ed (kN)

Concrete f_ck (N/mm²)

Steel f_yk (N/mm²)

Strut angle θ Auto (61.5° recommended) Custom (deg)

_c Bearing plate

Notes: Auto θ = 61.5° is taken from the worked example in your PDF. For rigorous strut capacity checks, you can override θ or complement this calculator with a strut-capacity check using strut cross-section and f_cd (not included here).
