Title: Comparison of Beam Deflection Variability in Members Using High Strength Concrete and Normal Strength Concrete
Author(s): B.-S. Choi and A. Scanlon
Publication: Special Publication
Appears on pages(s): 179-186
Keywords: beam; concrete; deflection; slab; variability
Abstract:Research has shown that design expressions previously developed for material properties such as modulus of elasticity, modulus of rupture and creep coefficient used in the calculation of beam deflections may not be appropriate for high-performance-high-strength concrete. Also, the uncertainties associated with regular and high-performance concrete material properties as characterized by probability distribution functions may be different. Since high strength concrete may be used to reduce the size of structural members, assessment of deflections will be an increasingly important design consideration. This paper discusses these issues and demonstrates through Monte Carlo simulation techniques some differences between the variability of deflections in beams made with regular and high-strength concretes.
