reinforced concrete prise
as per ACI , the ratio between column & beam concrete grades dont exceed 1.4
First make sure that the concrete is thick enough to attach a beam to. It should have a footing where you plan to install the beam. In your local hardware store there is a specific metal object that is used. I can't think of the name but basically the metal object sits on the concrete and looks like a large square cup that is sized for your beam and sits maybe 6" off the ground. The metal object is then attached to the concrete with special screws or nails that are inserted into holes that are drilled with a hammer drill and masonry bits. Once the metal mount is attached to the concrete, insert and level the beam and on each side of the "cup" there are spaces for nails or screws to attach the beam to the concrete.
It is a monolythic concrete beam consisting of a web and a flange to form the shape of a"T" .
If Ly/Lx >12 then the column is said to be long column where Ly is the length of column and Lx is cross sectional dimension (B or D) Long column has reduction factor and it frequently failed under local buckling. so introducing a beam at least every floor level, the column design/act as a short column..column stiffness also increased tieing with the beam..
reinforced concrete prise
It proves shear reinforcement in the beam.
as per ACI , the ratio between column & beam concrete grades dont exceed 1.4
M25 = 80 to 110mm in slab & beam M30 = 80 to 120mm in column

A beam will be placed horizontally, a column will be placed vertically.

beam
It is a monolythic concrete beam consisting of a web and a flange to form the shape of a"T" .
column
Anything which is supporting to a beam or column to eliminate the buckling failure due to high deflection and unbalanced eccentric load
