Structures or buildings which are so designed that various loads, such as Live load, Dead load,seismic load, are transferred from one component or element of the structure to another. Roof load to Beams to Columns to Footings to subsoil.
Reinforced cement concrete is the combination of ordinary concrete with reinforcement to increase its compressive and tensile strength to a greater extent.
We have already studied concrete has a very high compressive strength but low tensile strength.
Thus when only compressive loads are acting on the concrete surface then there is no need of using reinforcement in it.
But where tensile forces are also involved like in beams and slabs,there is high risk of failure when plain concrete is used.
Steel has very high tensile strength and also good compressive strength hence when these two materials, concrete and steel are combined together a material for construction is obtained which takes compressive, tensile and shear forces is known as a reinforced cement concrete.
