Dear Sefians,
Please refer for UPSTAND BEAM flange width in the experts Er.T.Rangarajan Forum for clarification and details.

Dear Er.Rangarajan

Thank you for your posting in the Experts forum

I think upstand beam with compression flange occurs in the case of cantilever beams with sunk slab [typically in porticos] and in the case of sunk slab near supports.

I understand that the reduction in flange width, in comparison with normal T beam flange width at midspan, is due to shear lag effect, caused by high shear force.

High shear force can occur near midspan also, when large secondary beams frame into a main beam. Here also high bending moment is accompanied with high shear forces.

Will it not be prudent to adopt the lower value of flange width in such cases [heavy points near midspan] also?
