Title: Experimental Study of Lateral Stability of Reinforced Concrete Beams
Author(s): Jagadish K. Sant and Richard W. Bletzacker
Publication: Journal Proceedings
Appears on pages(s): 713-736
Abstract:The study, which involves both experimental and theoretical phases, prov ides some basis for the formulat ion of design provisions for the lateral stability of reinforced concrete beams. Stability criteria, reduced to simplified formulas involving the ratios of I-/b and d/b, and based on conservative assumptions, are suggested for three types of loading commonly met in practice. The usefulness of these formulas limited to the under reinforced rectangular concrete beams. The experimental study consisted of casting and testing to destruction four groups of identical specimens all having an L/b ratio of 96 and a tensile steel content of approximately 3.85 with d/b ratios varying from 3.78 to 19.45. For the given strength of steel and concrete there exists a critical slenderness ratio, Ld/b2, beyond which instability is the primary mode of failure reducing the ultimate flexural strength. Experimental results verified the theoretical predictions for the test specimens.
