Dynamic experimental studies on lateral behaviour of batter piles in soft clay

A series of small scale dynamic experiments have been carried out on 2 × 1 model aluminum batter pile group embedded in soft clay. The batter angles vary from 0 to 20 degrees. The pile group is subjected to sinusoidal lateral loads of different magnitudes (20–90 N), constituting 20–40% of its static ultimate capacity with the frequency in the range of 1–120 Hz. The time history of pile head displacement and bending strain along the length of pile are measured. It is found that the peak lateral displacement and peak bending strain at resonance region decrease with an increase in the batter angle, particularly for higher magnitude of lateral loads.
