The elasticity of the material plays very important role in design and analysis of structures. In evaluation of deformation of members the magnitude of flexural rigidity plays very important role. The flexural rigidity depends upon elasticity of material and size of section used for particular member. Flexural rigidity increases as increase in the elasticity and size of the section. Time period of vibration structure affects the whole seismic design of structure. In seismic analysis the stiffness of structure affects the time period of vibration of structure. Stiffness depends upon the elasticity of material used in particular member. Hence elasticity of material used in member should be perfectly evaluated. Evaluation of elasticity of homogeneous material can be easily calculated by developing the stress – strain curve. But evaluation of elasticity of heterogeneous material is enough complicated to establish a standard mathematical expression. Reinforced Cement Concrete (RCC) is widely used construction material which is heterogeneous in nature. Many of the standard codes considers elasticity of concrete in design and analysis of RCC structure. Such codes neglects the effect of reinforcement on the elasticity of concrete. Considering only elasticity of concrete only in design and analysis of RCC structure will not give the exact value of deformations under loading as well as time period of vibration for seismic analysis. Underestimation of magnitude of elasticity may also increase the overall cost of structure. Hence there is an urgency to evaluate the elasticity of RCC precisely.
