Computer Analysis of Segmentally Erected Precast Prestressed Box Girder Bridges
The economic advantages of precasting can be combined with the structural efficiency of prestressed concrete box girders for long span bridge structures when erected by segmental construction. The complete superstructure is precast in box segments of convenient size for transportation and erection. These precast segments are erected in cantilever and post-tensioned together to form the complete superstructure. This report details the development of an analysis technique with an associated computer program to permit efficient analysis of constant depth segmental prestressed concrete box girders at all stages of erection. An existing box girder analysis program developed for analysis of completed structures was substantially altered to make it applicable to the multistage construction problem.
