Based on pull-out test of 16 specimens without stirrups,the bond behavior of ribbed bar and strand were investigated.Test results show that in the same bond medium,the bond strength of single ribbed bar is higher than that of single strand,however,the maximum slip value of the former is far less than that of the latter.No matter the reinforcement is single ribbed bar or single strand,the bond strength and maximum slip value between reinforcement and concrete are greater than those between reinforcement and ...
