Isolated footing Transfers individual column loads directly to the soil. If a single spread footing interferes with another spread footing, the two can be combined to form a combined footing.
where there the two columns faces overlap each other, when the column face is near to the boundary line
Combined footing
Yes, a concrete patio step does in fact need to be on a footing. Without the proper footing foundation, the step will be uneven.
Suppose a number of columns in a row are to be supported on a soil of such low bearing strength, that separate bases if provided would overlap,a practical solution would be to provide a column footing to support all the columns of the row. such a footing is called a "STRIP FOOTING"
Isolated footing Transfers individual column loads directly to the soil. If a single spread footing interferes with another spread footing, the two can be combined to form a combined footing.
You can calculate the quantity of isolated sloped footing by substituting variables for what you are trying to solve for. For instance, substitute x for rise and y for run.

Isolated footings are constructed invidually & Mat foundation is making of mat and connecting all footings with this mat
In general an Isolated footing has three parts. One Rectangular part another is Trapizoidal part and rest is Pedestrial part. The volume of concrete of rectangular part if AXBXH. The concrete volume of Trapizoidal part is h/3( AXB + aXb+ Sqrt(AXBXaXb) where h= Thickness of Trapizoidal portion, A & B are the dimensions of Bottom face and a & b are the dimension of top face. The volume of Pedestrial portion is aXbXD where D id depth of Pedestrial portion. Sum of three calculation gives you the volume of concrete of Isolated footing.
divide the footiing into two right angle triangles & a rectangle . calculate the area of rt < triangle & rectangle respectively,. the area so obtained when multiplied by length of footing gives quantity of concrete.
