It is a monolythic concrete beam consisting of a web and a flange to form the shape of a"T" .

Reinforced concrete is made by placing steel bars in the tension zone of the beam x-section.
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.
Almost any solid horizontal structural member is considered a beam. They are usually steel or concrete and are used to transfer a vertical load imposed on the span (middle) of the beam to the ends or vertical supports of the beam. Steel beams are probably what most people think of when picturing a beam. W-sections (formerly known as I-beams, but are modified by the strength/type of steel and the cross section shapes) are the most common steel beams used. Concrete beams are often used in foundations and can be best seen above ground in parking garages everywhere. There is always a good amount of reinforcing steel in a concrete beam to carry the tension that occurs in the bottom of a beam so the concrete won't fracture.
Stiffness is defined as the ratio of load per unit deformation.
Stiffness is defined as the ratio of load per unit deformation.
the spring stiffness effect the natural frequency of the beam. the increasing value of spring stiffness lead to the increase value of natural frequency of the beam also.

It proves shear reinforcement in the beam.
The flexural stiffness of a structural beam (E*I/L) is represented as the product of the modulus of elasticity (E) and the second moment of area (I) divided by the length (L) of the member.
to resist shear force
The neutral axis of a reinforced concrete beam is the area where the beam is neither in a state of tension or a state of compression. This is determined by having the length and breadth of the beam available.
check the fuses then check high/low beam switch
