Permanent Seismically Induced Displacement of Rock-Founded Structures Computed by the Newmark Program

Abstract

This research report describes the engineering formulation and corresponding software developed for the translational response of rock-founded structural systems to earthquake ground motions. The PC soft-ware Newmark and NewmarkVM are developed to perform an analysis of the permanent sliding displacement response for a structural system founded on rock for a user-specified earthquake acceleration time-history via a Complete Time-History Analysis, also known as the Newmark sliding block method of analysis. The PC-based program Newmark performs a permanent sliding block displacement analysis given a baseline-corrected rock site-specific acceleration time-history. Newmark can also conduct regression analyses for sets of rock-founded acceleration time-histories in order to develop up to three user-selected forms of generalized equations of simplified permanent displacement relationships. The rock-founded structural system can be a variety of structural feature types, for example, a concrete gravity dam, a concrete monolith, or a retaining wall.
