Cable-tied Concrete Block Erosion Protection
An articulated concrete erosion protection system is investigated as a possible revetment for bridge piers to be used in place of the traditional rip-rap revetment. The system consists...
Effects of Creep in Cable-Stayed Composite Bridges
The paper summarizes the various ways in which creep in the concrete slab may affect the stresses in a cable-stayed composite bridge. It explains one effect in particular which is not...
Hybrid Lifted Structure for the Collserola Tower
The structure of the 300 m. Collserola Tower is a hybrid system formed by three combined structural systems consisting of: - a very slender cylindrical concrete shaft: - a large steel...
Depth of Cover Surveys for Waterway Crossings
The majority of pipelines cross at least one waterway of some type, especially the interstate lines which from start to end cross numerous bayous, canals and major rivers. These waterways...
Database for Pipeline Bridges in North America
Work began in 1985 at Wayne State University on a research study of pipeline suspension bridges. This effort, which was funded by ANR Pipeline Company of Detroit, Michigan, investigated...
Plastic Potential
Some 220,000 tons of epoxy-coated steel has been used in the construction of bridge decks since 1987, but some have raised questions about its long-term durability. New materials for prestressing...
