Un-factored maximum bending moments at a section of a reinforced concrete beam resulting from a frame analysis are 50, 80, 120 and 180 kNm under dead, live, wind and earthquake loads respectively. The design moment (kNm) as per IS: 456-2000 for the limit state of collapse (flexure) is

1.2 DL+1.2 LL+1.2 EQ = DESIGN MOMENT.
1.2*50 + 1.2*80 + 1.2*180 = DESIGN MOMENT.
60+96+216 = DESIGN MOMENT.
DESIGN MOMENT = 372.
1.2*50 + 1.2*80 + 1.2*180 = DESIGN MOMENT.
60+96+216 = DESIGN MOMENT.
DESIGN MOMENT = 372.

What about wind load?

Design moment = maximum of 1.2(DL + LL + EQ/WL).

Then why wind load is given when it is optional.

Wind load is given because this question is for GATE examination. Just for the sole purpose of creating confusion.

@Mr. Anurag.
If there is seismic wave then the effect of wind is neglected, it is not optional.

Is it every time possible that, wind load is always less than earthquake load?

Assumed as wind and earthquake forces will never act together, so seismic only considered.

Here, the seismic load is maximum w.r.t wind load, so the seismic load is considered.

Wind load and earthquake load not consider together.
