| Abstract: | Grey correlation analysis was conducted to study the performance-influence parameters of the clamping anchor for CFRP(carbon fiber reinforced polymer) rods.The two parameters were taken into consideration: the individual torque applied to the bolts(from loaded end to free end) and the total torque.Based on analytical results,the sequence from the high correlation of ultimate load to low correlation is: the individual torque applied to the third row of bolts,the total torque,the torque applied to the second ... |
