Checks

First you get an overview of the input data for the checks:

• Internal forces, displaying the characteristic and design values.
  For member type 'column', the design values of the bending moments include the 2^nd order bending moments (if required) and the moments due to geometric imperfections.
  For member type 'beam', the design values of the bending moments include the shifting of the moment line - to take the additional tensile force due to shear into account.
• Slenderness calculation (for member type 'column'), determining if 2^nd order effects need to be taken into account.
  
• Stiffnesses, displaying the values EA, EI_y and EI_z.

Available checks at the Ultimate Limit State:

• Capacity check for N-M_y-M_z interaction - based on resistance calculated from interaction diagram
• Response check - based on check of ultimate stresses and strains for N-M_y-M_z interaction
• Check of shear and torsion
• Check of interaction of shear, torsion, bending and normal force
• Check of detailing provisions

Available checks at the Serviceability Limit State:

• Stress limitation (for concrete as well as reinforcing steel)
• Crack width limitation
• Simple check for deflection - based on calculation of stiffness ratio, without necessity to calculate Code dependent deflections (CDD)
