Book Description
The objectives of this investigation were to evaluate the latest prestressed concrete bridge girder designs being used in the United States and to determine which represent optimum designs that could be promoted as national or regional standards. Bridges built with pretensioned I- and T-sections for spans in excess of 80 ft (24.4 m) and concrete compressive strengths up to 7000 psi (48.3 MPa) were considered.

Book Description
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
