It is possible. We have done a beam of span 17.5m for the balcony of a community hall (shown in the picture). You can check the deflection of the beam by the criteria given in Cl: 23.2 & 24.1 of I ...

Really shocking news...
Prabhakar sir was an active participant in the discussions of SEFI till recently.....
May the departed souls rest in peace.

Steel beam theory will return very meagre value of moment of resistance, owing to the low value of lever arm.

Dear sefians,
How to calculate BM @ face of support & SF @ distance d from face of support from values obtained from centreline analysis...? Is linear interpolation resonable??


If you are us ...

Sir,
How can we work out the moment capacity of a hidden beam illustrated by you ? Probably by steel beam theory ? The moment of resistance will be very meagre, I hope.

I think, the concept of Hidden Beams is fallacious. There is hardly any literature that advocates the use of hidden / concealed beams in slabs of normal thickness, along with theory to establish its e ...

Dear Sefians,

For design of corner column footing with eccentric load, the best solution for stability consideration is to tie the corner footing to an adjacent column footing with a beam. The exam ...

Er. Moosewla,
If compression steel is provided in an RCC slab, making it doubly reinforced, there will not be any substantial gain in its Moment of Resistance value, perhaps due to the low value of L ...
