Abstract
The lateral forced vibration test was carried out on driven cast in-situ concrete vertical piles of 500 mm diameter in a petrochemical complex site in Paradip, India. The site predominantly consists of silty sand for the top 3 m with shear wave velocity of 200 m/s and it is followed by clayey sand with shear velocity increases from 415 m/s to 460 m/s over pile termination depth of about 17 m . The piles were subjected to a sinusoidal lateral force with magnitude of 0.3 kN to 9.5 kN in the frequency range of 5 to 30 Hz. A 3D finite element analysis was carried out on vertical piles using ABAQUS and its results are validated with the field test results. Finite element analysis was extended to batter piles (10˚and 20˚) subjected to lateral dynamic load and it was found that the peak displacement amplitude of batter piles is 15 to 25% less than the same that of vertical piles indicating better performance of batter piles under lateral dynamic loading.
