Structural Systems in Support of Safety: New Highway Structures Design Concepts. Volume II. Preliminary Designs and Engineering Data

摘要

The document is volume 2 of a 3 volume report. It contains results of the program presented as artist's sketches, tabulations of engineering data, preliminary design drawings, design assumptions and criteria, and cost estimates for the fabrication of prototype structures, along with subsequent procurement in quantity. Three new bridge concepts which employ cable supports are advanced as feasible structural schemes for effecting the removal of massive support structures from the area adjacent to the roadway. Cable-supported structures concepts for highway signs and lighting systems are also presented. (Author)
