Notes:

1- Increasing adopted longitudinal reo changes the beam's bending & shear capacity (epsilon, Kv)

2- The value Asv/S is inclusive of shear & torsion requirements (AS3600-2018-A1)

3- This module assumes the beam is provided with shear reinforcement equal to or more than the minimum ratio. Kv calculation is done to clause 8.2.4.2.1(b)

4- Deflection check button should be clicked on everytime reo is updated by user

5- The progam will give error if tension reinforcement ratio exceeds 3% & compression reo >1%, or Ku>0.545. Avoid over-reinforcing by increasing size MPa

6- If compression reo is required, provide 1% in adopted top, for non-ductile section per the Australian Standard

7- For SLS checks, RKALC is adopting Reinforced Concrete Buildings Series, Design Booklet RCB-1.1 (1) available at this link. Ensure to establish the correct criteria for Crack Width calculations, inlcuding exposure conditions and required degree of crack control
