AASHTO LRFD Bridge Design Specifications provisions for loss of prestress

摘要

I would like to compliment Brian D. Swartz, Andrew Scanlon, and Andrea J. Schokker on their exceptional paper titled "AASHTO LRFD Bridge Design Specifications Provisions for Loss of Prestress" in the Fall 2012 issue of PCI Journal. This is a resource that engineers will refer to for years to come. The American Association of State Highway and Transportation Officials (AASHTO) T-10 committee on concrete is beginning the process of reorganizing and clarifying the requirements in section 5 of the AASHTO LRFD Bridge Design Specifications. I would be curious to know specifically how the authors would modify the AASHTO LRFD specifications to clarify the prestress loss and elastic gain provisions.
