USE OF FOUNDATION UPLIFT TO LIMIT BRIDGE PIER FORCES. A REPORT ON RESEARCH PROJECT 48221

This report covers investigations into some aspects of foundation uplift as a means of limiting pier and deck forces in the seismic design of bridges. A limited computer study was carried out of the reponse of a small number of wall type piers to various ground acceleration records. Seven analyses were made to provide a basic parametric study of the effects of pier aspect ratio, foundation soil type and earthquake record. This study was carried out to determine the direction for further and more intensive work on aspects of design for rocking. (TRRL)
