Structural Systems in Support of Safety: New Highway Structures Design Concepts. Volume I. Research Information

摘要

The document is volume 1 of a 3-volume report. It summarizes research activities conducted in response to requirements for developing new, cable supported structures design concepts that will permit removal of massive support structures from the area adjacent to the roadway. Development efforts are discussed in identification of bridge concepts and sign and lighting system concepts that are responsive to new, safety related design criteria. Sixteen bridge concepts were examined with respect to their potentials in responding to the new criteria; eight of the sixteen design schemes were selected for subsequent preliminary analysis and concept designs. Similarly, four sign support structure concepts and four lighting system support structure concepts were selected for preliminary analysis and concept designs.
