In order to estimate the effects of cyclic loading on bearing capacity and pull-out resistance of piles, monotonic and cyclic vertical loading tests were conducted on a pile with or without spiral wings in uniformly graded sand in a calibration chamber. Both pushing and pulling shaft friction decreased with increasing the cyclic loading force, whereas the pushing end wing and tip resistance did not decrease with increasing the cyclic loading force.doi:10.3130/aijs.81.725 fatcat:m2rcmujccndadppty3ndafsueq
