ROCKING COLUMNS: AN EFFECTIVE MEANS OF SEISMICALLY ISOLATING A BRIDGE

This paper describes the seismic resistance of a rocking bridge pier both with and without the effects of prestress. Although the subject of rocking structures is not new, dating back to the early work of Housner in 1963, much of the work that followed was aimed at investigating the sesimic response of rigid rocking block systems. Although Meek in 1978 introduced aspects of structural flexibility coupled with rocking structures, and Aslam et al. in 1980 considered the influence of prestress that provided some resistance in anchoring a rigid structure to the ground to increase its rocking resistance, neither investigator specifically addressed issues pertaining to bridge structures. Only recently did Priestley et al in 1996 describes in their monograph the behavior and design of rocking bridge piers. However, Priestley et al. did not integrate the inter-related aspects of rocking, structural flexibility and prestressing in their design recommendations. This paper attempts to address these issues and to present unified analysis and design procedures.
