Application of the Strength Design Method for Flexural Members at Prestress Transfer

摘要

align="left">This paper illustrates the application of the theory presented in “Strength Design of Pretensioned Flexura I Concrete Members at Prestress Transfer,” published in the January-February 2001 PCI JOURNAL. That paper recommended that working stress design of prestressed members at time of transfer of prestress to concrete be replaced with strength design. This paper shows how this theory could be implemented using a standard spreadsheet program, such as Microsoft Excel. A parametric study justifying relaxation of the load and resistance factors proposed in the earlier paper is summarized.? Applications to standard products such as I-beams, inverted tee beams and double tee products are given.
