Some days ago I have posted a Picture of an eccentric isolated foundation and I asked my fans on facebook that whether it is right to place an isolated column foundation like this or not?
As a result I have got some very useful and insightful comments of my fans which i though I must share with you on the subject of eccentric footing, cantilever footing or shoe footing.
No strap beam? Thats just not right. The footing cant handle the moment due to eccentricity of the column. Property footings require strap beam so as to handle the moment and for the footing to act as a double cantilever footing.
It is right..This type of footing is called shoe footing….For this type of footing required more depth and heavy steel..I was cast like this type of footing on site .. Mostly use when space is very less ..

Its eccentric footing use mostly to the property line.if it a multi story builing need to connect with other footing such is strap beam/combine footing to avoid tilting of the footing.
If load is less than no problem but provide a strap beam in footing equal to length of footing only no need to connect with another footing
if it is a single.storied.building no.issue.but for a multisrotied building better to plant a column at the.eddge of.the.footing untill meet a strap.bram at the tie.beam.level
No blinding layer. No cover. No strap beam. Wrong
