Fracture Behavior of Concrete Beam Subjected to Dynamic Loading

동적하중을 받는 콘크리트보의 파괴거동

In this study, after concrete cylinders were made on the condition of varying water-to -cement ratio, and cured 80 days compressive strength and splitting tensile strength were performed and moduls of elasticy is obtained. The fracture energy was obtained by acting three point bending on the 80cm in length. This test involved static loading test and dynamic loading test. In this work, the new interrelation of the material constants was obtained clearly and the property of the mixture was inspected, including the relation between the fracture energy and all kind of the material constants.
