Available in PDF, EPUB and Kindle. Book excerpt: The objectives of this investigation were: to identify the limitations of existing prestressed concrete girder cross sections relative to the use of high-strength concrete; to examine the feasibility of using modified cross sections to take advantage of the high-strength concretes; to investigate the use of alternative construction systems; and to define factors that limit the application of high-strength concrete. The research was performed using the computer program "BRIDGE" to determine relative unit costs and maximum span lengths for different simple-span prestressed concrete bridge designs
