Full-scale experimental study of the seismic performance
2022年11月1日 Once the failure of PHC piles turns to be controlled by the crushing of concrete under a higher axial force, the ultimate drift decreases with further increase of the axial force ratio. For the particular pile considered herein, the failure of the pile tends to be dominated by the crushing of the concrete with an axial force ratio higher than 0.15.
