Description
Summary:The seismic response of marginal wharf segments is considered based on simple analytical relationships, and dynamic inelastic time-history analyses. Of particular interest was the amplification of transverse displacements caused by torsional response under longitudinal excitation, and the magnitude of shear key forces developed at movement joints between adjacent wharf segments. Different assumptions were made about pile stiffness, particularly recognising the differences resulting from unequal foundation stiffness and strength in the upslope and downslope directions. Simple design recommendations were verified or calibrated against the time-history results.
