STUDY ON CONSTITUTIVE EQUATION OF HIGH STRENGTH CONCRETE TO UNIAXIAL DYNAMIC COMPRESSION

This paper adopts the non-linear elastic constitutive model, bases on relationship types of high strength concrete to uniaxial dynamic compressive strength, elastic modulus and strain rate, introduces strain rate correction factor for a similar amendment to the constitutive model, then establishing a constitutive model of high strength concrete to uniaxial dynamic compression, and apply experimental data to verify the correctional constitutive model.
