STUDY OF DYNAMIC COMPRESSIVE PROPERTIES OF CONCRETE
Dynamic loading to the rock structure and concrete structure is inevitable during use; such as wind load, seismic load and explosion impact load for underground rock structure. Dynamic load is an important factor for structure design. In this paper, the uniaxial dynamic compressive test was carried out on concrete specimens under different stain rates using a large static and dynamic electro-hydraulic servo testing system. The effect of stain rate on concrete failure modes, compressive strength, elastic modulus, peak strain and Stress-Strain curve are studied. The experiential formula for dynamic strength of concrete which changes with strain rate is given. The test indicates that the concrete compressive strength increases with the elastic modulus and peak strain also increases as the strain rate goes up.
