Cracking Analysis of the Upset Head of PC Steel Bars
The PC steel bars were cold-headed and the upset heads were not cracked in the process of the PC steel bars. The upset head of PC steel bars were analysed and tested by means of tensile test and metallographic structure examination. The results showed that the cracking has some relationship with the strength grade of the PC steel bars, and the preventive methods were also proposed to avoid similar events.
