ShortCol - axial/flexural investigation of reinforced concrete member

With ShortCol spreadsheet one can design reinforced concrete members such as columns or beams for combined action of axial force, bending moment, shear and torsion in accordance with the building and bridge codes of USA, Canada and Australia. Shortcol uses strain compatibility analysis to accurately assess ultimate flexural capacity and crack control at service loads.

• Computes uniaxial and biaxial ULS axial force/bending moment interaction diagrams
• Performs service limit state analysis to assess crack control and distribution of tensile reinforcement
• Computes shear and torsion resistance
• Allows circular, rectangular, chamfered and T-beam cross-sections
• Computes 'cracked' section properties at ULS
• Allows to quickly define typical and irregular reinforcing steel layouts
• Features US and SI units
• Conforms to ACI 318, AASHTO, AS3600, AS5100.5, CSA A23.3 and CSA-S6 design codes

• Does not consider column slenderness (yet)
• Biaxial analysis is not precise, it uses interaction formulas between two major axes
• Limited to 200 reinforcing bars
• Does not accept prestressing steel
• Does not accept unbonded steel
• Uses equivalent rectangular concrete stress distribution for ULS, triangular stress distribution for SLS
