Parametric Results for Seismic Response of Pile-Supported Bridge Bents

摘要

A complete set of parametric results in the form of graphs and tables arepresented for the seismic response of bridge bents supported either on a single drilled pile or on a 4x5 pile group embedded in three actual layered soil deposits. The seismic excitation, in the form of vertically propagating S waves, is described through real and artificial accelerograms applied at the base of the deposit. Both kinematic and inertial interaction are taken into account. Results are presented (in both frequency and time domains) for accelerations and displacemnets of the bridge and the pile cap, as well as for internal forces along the piles.
