The structural behaviors of preliminarily cracked members and artificially cracked member are sometimes different from that of general RC members. It owes to crack path dependency that is unique to RC members. It is known that the effect is subjected to the direction and location of artificial crack. In this study, it is experimentally revealed that horizontally arranged ACD improves tied arch effect resulting in further shear capacity. Hence, optimum location and position of ACD are proposed and required condition is denoted.
