Title: Creep of Prestressed Concrete Beams
Author(s): W. S. Cottingham, P. G. Fluck, and G. W. Washa
Publication: Journal Proceedings
Appears on pages(s): 929-936
Abstract:Presents test results obtained during 7 years of sustained loading of six prestressed concrete beams. Each beam was end-supported over a PO-ft span and uniformly loaded. Two beams were loaded to full design load, two were loaded to 3/4 design load, and two were loaded to 1/2 design load. Creep deflections and creep strains measured during the 7 year loading period are reported. Deflection and strain recoveries due to removal of the loads and for 64 days after load removal as well as the final failure loads for the beams are reported.
