| Abstract: | In this paper, the method of fracture mechanics is used to analyse cracked reinforced concrete members. Experiments and calculation with finite element method are performed and the values of linear elastic fracture toughness kIc for cracked reinforced concrete members are obtained. Effects of the ratio of span over deptl s/w and the size effect of reinforced concrete members on the value of kIc are also studied. Acoustic emission technique is applied successfully in testing to indicate the critical cracking point of every reinforced concrete beam. |
