This report presents a research study conducted to predict the impact forces that occur when a barge train impacts head-on with a circular concrete or concrete-filled structure. These structures are found at the end of lock approach walls as semicircles called bullnoses, as circular cells, and as mooring cells. This research was conducted using finite element analysis. A detailed finite element model of the bow of a jumbo hopper barge ...
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 ...
