摘要

Prestressed concrete tub girders curved in plan (hereinafter abbreviated CPPCG) have seen increasing use in Colorado as a substitute for steel I/tub girders or cast-in-place, post-tensioned concrete box girder systems. This presentation will cover design, fabrication, and shipping/erection issues as well as owner-related considerations. Multiple metrics will be used to compare this system to more traditional structure types. Examples from projects built or in the construction stage will be given.
