The Required As reported in the Audit Report is the lower limit in 9.3.1.1(1): 0.0013*b*d. In your screen capture, you will see that the Design As is 773.8 mm^2. This is the required area of steel that the program is designing to satisfy the code minimum requirements. This value is calculated as follows:
fctm = 0.3*(35)^(2/3) = 3.21 MPa
fyk = 500 MPa
b = 2136 mm
d = 217 mm
As,min = 0.26*(3.21/500)*2136*217 = 773.7 mm (differences due to rounding)
fctm = 0.3*(35)^(2/3) = 3.21 MPa
fyk = 500 MPa
b = 2136 mm
d = 217 mm
As,min = 0.26*(3.21/500)*2136*217 = 773.7 mm (differences due to rounding)
