RC Beam Shear and Torsion Calculator | CSA A23.3-14
Check reinforced concrete beam capacity under combined shear and torsion per CSA A23.3-14. The calculator evaluates concrete contribution, required stirrup reinforcement, and combined shear-torsion interaction. Input beam geometry, concrete strength, reinforcement layout, and applied forces to verify the design meets code requirements. Full hand-calculation output with all intermediate values.
Does the calculator handle combined shear and torsion?
Yes. It checks the interaction between shear and torsion demands per CSA A23.3-14 and determines if the cross-section and reinforcement are adequate for the combined loading.
What stirrup configurations are supported?
Closed stirrups (required for torsion) and open U-stirrups (shear only). The calculator determines the required spacing for the governing load combination.
Can I check if torsion is negligible?
Yes. The calculator compares applied torsion to the threshold torsion per CSA A23.3-14 and indicates whether torsional effects can be neglected.
