PCC / Gravity type WallsConcrete – M15 Grade with and Without plum concreteSteel – Fe415 Grade with Min. Surface R/F 12 @ ----- c/c

R.C.C. Cantilever / Counter fort WallsConcrete – M20 Grade and Steel Fe415 as required as per theory of bending using working stress method.

Height for all Walls = 10.0 mLength of wall considered = 30.0 m

PCC / Gravity type Walls Assumed to be founded on hard Rock, hence designed for at

rest pressure being Gravity type wall.

R.C.C. Cantilever / Counter fort Walls Assumed to be founded on hard Rock and designed for

critical condition governing from Active / passive pressure.
