The Evolution of Pipeline Suspension Bridges in North America Since 1952

This paper summarizes published and unpublished work in the areas of design and construction, analysis and retrofitting, and security of pipeline suspension bridges in North America over the past 50 years. The published work of many prominent civil engineers and civil engineering researchers is discussed. The basic types of pipeline suspension bridges and articles that have been written on the design and construction of pipeline suspension bridges since 1952 are presented. The pipeline suspension bridge analyses that are described include wind and seismic analyses. The retrofitting methods presented include modifications made to pipeline suspension bridges to eliminate vertical wind oscillations and proposed retrofit methods for improving the earthquake performance of pipeline suspension bridges. The security measures used to restrict unauthorized access to pipeline suspension bridges are also discussed. Recommendations regarding the improvement of security for pipeline suspension bridges are also presented.
