摘要: An experimental study of the confined compression behaviour concrete has been performed using 100 mm cubes. The compressive strength, splitting tensile strength and ultrasonic velocity are measured before after loading history, respectively. Based on continuum damage mechanics theory, reduction denote concrete. relationship between decrease owing to triaxial history is investigated. According fitting data, evolution equation obtained. found be in a linear dependence with velocity. It concluded that, being an important non-destructive detection method, inspection convenient applicable estimation under various patterns engineering practice.
