Beam Design Limits.
Minimum beam depth is controlled automatically.
Deflection limits is controlled automatically.
International Design Codes
ACI 318-19 : Beam Design Limits per ACI 318-19 with ideCAD

Notation
Ag = gross area of concrete section, in2
bf = effective flange width, in.
bw = web width or diameter of circular section, in.
c1 = dimension of rectangular or equivalent rectangular column, capital, or bracket measured in the direction of the span for which moments are being determined, in.
c2 = dimension of rectangular or equivalent rectangular column, capital, or bracket measured in the direction perpendicular to c1, in.
Ec = modulus of elasticity of concrete, psi
Es = modulus of elasticity of reinforcement, psi
