To the members
I have a question on the design of footings
Top reinforcement is a must for footings with loss of contact ( gross pressure is tensile).
I feel we need to provide top reinforcement if the net pressure on any one side of cantilever span is tensile.
Some people do not accept this
Please mail your expert opinion on this.
For clarity , I have attached excel file to admin@sefindia.com

To Mr. B. R. Seshasayee,
Dear Sir,

In reality Tensile pressure is fictitious!! When footing loses it's contact
with the soil, pressure gets redistributed on the balance area, which is in
contact with soil. Thus the magnitude of direct pressure gets increased on
balance area. Naturally the moment also increase, requiring greater
reinforcements. Whereas the area, which has lost the contact with soil has
theoretically only selfweight acting on it (and the soil-surcharge if any)
thus the moments will be usually less, which may be checked for the
requirement of top reinforcements.

Further the loss of pressure should not be permitted. If permitted, it
should be limited to minimum.
