Why is the main reinforcement provided on the longer side of raft footing?
Pile foundation and raft foundation is used for a high rise structure. Pile foundations are more capable of taking higher loads than spread footings. When allowable bearing pressure is low, the heavy structure is present & the site is with a highly compressible layer; then raft foundationRead more

When allowable bearing pressure is low, the heavy structure is present & the site is with a highly compressible layer; then raft foundation is applicable.
Thank You.

The longest span is in more critical section due to which main reinforcement is provided on the longer span. The longest span has to bear a higher bending moment. This is because the uplift pressure from the soil below will be equal in all locations, but the moment developed at the longer span willRead more
The longest span is in more critical section due to which main reinforcement is provided on the longer span. The longest span has to bear a higher bending moment. This is because the uplift pressure from the soil below will be equal in all locations, but the moment developed at the longer span will be higher because of a long arm. Its a uniformly distributed load and so it produces a larger moment on a longer beam. Thus, the main reinforcement is provided in longer span.
