Dear All

1.15 factor is used for shear developed due to moment in flat slab if results of moment are not available.
is this factor require to apply for isolated footings?
Example-
shear from column say-100ton
facotred=1.5x 100=150ton
for moment transfer for internal columns= 1.15x 150=172.5ton.
this shear is considered for punching check.

my Q. - is the factor 1.15 is necessary to use for footing?
our one of the client is saying to avoid it as soil is around the footing.
