RELILABILITY OF SHORT COMPOSITE BEAM-COLUMN STRENGTH INTERACTION

This study simulated the statistical properties of the short time ultimate strength of short composite beam columns in which steel shapes are encased in cast-in-place concrete. The material strengths and geometric properties were varied randomly and the resulting variations in the ultimate strength were determined. The study results indicate that the probability distribution properties of strength of short composite beam columns are influenced most signigficantly by the specified concrete strength and the end eccentricity ratio, and to some extent by the ratio of area of structural steel section to gross area of the cross section. The study shows that the effects of structural steel grade and strain-hardening of steel can be neglected. The strength statistics suggested in the paper will be useful for future evaluation of probability-based resistance factors for short composite beam-column strength.
