Shear

Shear Resistance of an RC Beam — Interactive Calculator

Enter beam and reinforcement data. Results show intermediate calculations (units shown). Based on typical Eurocode-like design equations illustrated in your example.

Beam width, b_w (mm)

Effective depth, d (mm)

Characteristic concrete strength f_ck (N/mm²)

Characteristic steel strength f_yk (N/mm²)

Stirrup/bar diameter (single leg), Ø (mm) — for info

Number of legs (per link)

Area of one bar A_bar (mm²) — leave blank to auto-calc from Ø

Stirrup spacing, s (mm)

Ultimate uniformly distributed load, w_u (kN/m)

Span length L (m)

Support width (used as contact width) b_supp (m)
