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
-
- 195
- 250
- 345
- 372
Correct Option: D
As per IS: 456 - 2000 only earthquake or wind load need to be taken. Here higher is earthquake load (= 180 kNm). Hence it is considered for design.
∴ Factored Design moment = 1.2 (50 + 80 + 180) = 372 kNm
