In this study, concrete fracture energy was obtained using Hillerboug's three point notched beam test. Total of 12 notched concrete beams were tested under the two different loading conditions: constant stroke control and constant CMOD control. Even though individual fracture energies obtained from two different loading condition show some of variations, averaged fracture energy from both loading condition were very similar.
