Structural Evaluation of Diagonal Riders for the USS CONSTITUTION

Abstract

A study of the addition of diagonal riders to the USS Constitution to prevent hogging is described. The purpose of the diagonal rider structure is to reduce the hogging rate of the ship and to help restore the ship to its original as-built condition of 1797. The study employed both analytical and experimental methods to determine the effect of the riders on the bending response of the ship. The goals of the study were to determine the hogging rate reduction produced by the riders and to develop an improved understanding of the mechanisms that cause hogging in wooden ships. Recommendations are made to further reduce the hogging rate and to install data acquisition systems both for short-term and long-term structural monitoring.
