In connection with inspection and testing of concrete structures as per IS 456:2000, while conducting load tests on flexural members, what is the load (L) and minimum duration of load application(T) on the structure? (Use notations as : DL : dead Load, IL : Imposed load)
1
L = DL + IL ; T = 48 hours
2
L = DL + 2 × IL ; T = 7 days
3
L = DL + 1.25 × IL ; T = 24 hours
4
L= DL + 1.5 × IL ; T = 72 hours
