Any RCC section is a concept of Monolithic section that serves as a structural member bearing Tensile, compressieve and flexural stress . While Concrete has a substantial capacity of Compressive strength, it's capacity of Tensile strength is only marginal. Reinforcement steel is generally used as to impart required Tensile strength which may be developed either by bending stresses( Under Flexural Load ) or under direct tension. However, sometimes it may so happen that the RCC section has to be restricted within a specified limiting dimensions due to architectural or functional constraint. This limiting size of the RCC section may leads to insufficiency in the required capacity of Compressive strength purely by concrete section. Additional reinforcements are therefore necessary to compensate the area of concrete requred in the compression Zone. These are called Steel in Compression Zone and such section using Steels both in the tension as well as compression is called a Doubly Reinforced Section.

Along with the restriction on cross section..when there is a load reversal as in the case of earthquakes there might be tension in the compression zone which will be taken care of by the reinforcement present there.

How much number of maximum bars are provide in compression and tension zone
