Elastic modulus of concrete 57000
WebAbstract: At present, the modulus of elasticity, creep and shrinkage properties of concrete that are used in structural design in Florida are based on the arbitrary available literature … Web2. Modulus of elasticity. The modulus of elasticity of concrete used to compute deflections, a period of vibration, and drift of structures. It is calculated using equations that are provided by ACI 318-19 Code or testing. There are differences between values obtained from equations and those achieved from testing.

WebModulus of the elasticity can be tested by compression test. The Young's modulus of the concrete given in ACI 318 is: E c = 57000 f c in psi or E c = 4700 f c in MP a In which, f c ′ is the strength of the plain concrete, and influence of reinforcement is not included. The Young's modulus of reinforced concrete members can be determined by tests.
