Title: Creep and Shrinkage Data for Elevated Prestresses Concrete Guideways
Author(s): H.G. Russell
Publication: Journal Proceedings
Appears on pages(s): 124-133
Keywords: age; beams (supports); camber; compressive strength; creep properties; cylinders; deflection; girders; guideways; modulus of elasticity; Poisson ratio; prestressed concrete; prestress loss; research; shrinkage; thermal expansion.
Abstract:The results of an experimental investigation to determine the time-dependent properties of materials for large prestressed guideway girders are reported. Both elastic and long-term creep and shrinkage deformations were measured on standard 6 x 12-in. cylinders and on full-size reinforced concrete beam sections. Comparisions of the results were used to determine the effect of size on creep and shrinkage. Extrapolatation of the data to other sizes of guideway girders is presented. The results of this study, obtained over a period of two years, can be used in the calculation of camber and axial shortening in girders.
