Reinforced Concrete (RC) Design Calculator & Engineering Guide - AluCalc
Calculates the required reinforcement steel for concrete structural elements according to limit state design.
Formula
M_u = \phi A_s f_y (d - \frac{a}{2})
Mu= Flexural strength
As= Rebar area
fy= Yield strength
d= Effective depth
