Design Guide for Prestressed Concrete Long-Segment Bridge Girders
The steps required for the design and analysis of two-span prestressed concrete bridge girders made from three long I-section segments joined end-to-end are described and discussed. The three segments are erected on the three final and two temporary supports, and are then joined. In one bridge subtype, the structure is post-tensioned after the joint area and deck concrete has been cast and cured. In the second subtype, reinforcing bars extending into the joint are spliced before the joint and deck concrete is cast. The temporary supports are later removed. The second bridge type is a hybrid structure that is partly prestressed concrete and partly reinforced concrete, and the design criteria used are extensively discussed. This design guide is a continuation of experimental and analytical work completed earlier, and that work is referenced at appropriate points. Two post-tensioned structures using the concepts described here have been built in Illinois, and some experience gained from the first of these is also reflected in this report.
