The Influence of Ratio of Reinforcement to Modulus of Elasticity of Reinforce Concrete Component

Abstract:

Modulus of elasticity is an important mechanical parameter in analysis and design of reinforce concrete structures. The present value of modulus of elasticity ，which has rare relation with ratio of reinforcement ，is based on plain concrete. Authors deduced an equation between modulus of elasticity and ratio of reinforcement, and then an experimental study was conducted on 11 groups’ component of reinforce concrete with different ratio of reinforcement. At last, an equation for modulus of elasticity of different ratio of reinforcement determined by regression, using least squared method, was described. A cantilever, whose dynamic characteristics and response were calculated, was taken as an example to analyze influence of ratio of reinforcement on the structural analysis .Result shows that ratio of reinforcement has effect on modulus of elasticity . Moreover, if general modulus is ignored when calculate dynamic response, it will cause deviation.
