Performance of Under-Reamed Piles Subjected to Harmonic Vibration Considering Geometric Variation
This study aims to investigate the performance of under-reamed piles under vertical harmonic vibration. A 3D finite element model has been developed and the effect of geometrical features of pile like aspect ratio, number of bulbs, and bulb spacings are being explored in this study. Under-reamed piles having a stem diameter of 0.2 m and bulb diameter of 0.5 m, under eccentric moments of 0.005 kg-m, 0.01 kg-m, and 0.02 kg-m were considered. Variations of geometries included length of the pile (4 m, 5 m, and 6 m), aspect ratios (20, 25, and 30), number of bulbs from 1 to 3, and bulb spacing (0.5 m, 0.75 m, and 1 m). The study concluded that an increase in length and bulb numbers highly influenced the performance of under-reamed piles by reducing amplitude to a better extent. However, an increase in spacing between bulbs exhibits negligible variations in resonant amplitude when subjected to dynamic loading.
