الملخص

This paper presents the results of experimental study on strength and behavior of repairing rubberized reinforced concrete knee joints with carbon fiber reinforced polymer (CFRP)sheets under bending moment tend to open the angle. A total of eighteen specimens with square cross section legs (150 mm×150mm) and length of legs (550 mm) were prepared and tested up to failure. Test parameters were the percentages of rubber aggregate by weight of coarse aggregate ( 5, 15 ,25 )%, length of rubber aggregate (1,2,4,6)mm, types of reinforcement details in corner region( simple or loop) and method of repairing with CFRP (U or L shape). The effects of these parameters on strength and behavior of knee joints are studies ,The results of the study demonstrated a decrease in cracking and ultimate moment strength of specimens with increase percentage and length of rubber aggregate, and significant increase on the strength of repaired knee joints compared with its original.
