Depends on what the footing is holding. Typically, the reinforcing is place each direction in the bottom 3" of the footing. A top mat is sometimes required as is verical and horizontal bands, again dependent on the application required. The project engineer should have a designation of what and how much reinforcing is reqd.

Is rebar needed in concrete footings for posts?
If the posts are to support a structure such as a house or barn, yes. If the posts are to support a rail-fence, no. Check with your local municipality's code enforcement office for permit requirements. Then draw, draw, draw!
How do you strengthen concrete with reinforcing rod?
Rebar is used to strengthen concrete because of its strength and flexibility. In order for these rods to work, there must be ample space between the rebar and the edge of the concrete piece.
What is the difference between lap splice length and development length for rebars?
The difference between the two is in the application. A development length is the amount of rebar length that is needed to be embedded or projected into concrete to create a desired bond strength between the two materials. The lap splice length is the length two rebar pieces must overlap and be tied together to create a bond as if there was no break and the run is "continuous". So simply put, development is rebar to concrete, splice is rebar to rebar. The lengths of both splice and development do vary. They are dependent upon different factors. These include but are not limited to concrete strength, rebar size, rebar coating and concrete cover or clearance. So when you see a chart on one project, it can differ from another for these reasons.

Why do builders put metal rods in concrete?

Do you have to pour all your concrete footings at once?
You should or at least each wall at the same time. You could pour it in sections as long as the rebar was joining each section. The problem would be at the joints. How to form up a section of the footing with the re bar in place. If the rebar is not tied together, the wall will move and never be what it should be.

How much steel required for 1meter cubic of conceret?
It depends on how much rebar you're willing to lay down, in earthquake prone areas and structural concrete you'll generally see a lot of rebar, in just normal paver concrete you may not see any. Rebar is used to give concrete flexibility without brittleness so it really depends on the use of the concrete.
Is epoxy required in rebar connections?
Epoxy is not required in rebar connections as concrete and wire are used to hold it in place. Rebar is a reinforcement place inside masonry structures to provide increased strength.
