Abstract:
Describes recommended design procedures for hollow reinforced concrete box bridge piers and pylons with thin walls, which may be susceptible to local wall instability. Both monolithic cast-in-place construction and segmental precast construction are discussed. An overview of available studies on thin-walled box piers and pylons is presented, including an experimental and analytical study recently completed at the University of Texas at Austin. The current state of practice for the detailing of hollow piers and pylons is reviewed. Design code provisions, both domestic and foreign, are also summarized. Finally, general criteria methods of analysis of concrete box columns are outlined, and specific recommendations for detailing of reinforcement are presented.
