Abstract
A research study was performed to investigate the discrepancy in shear capacity calculated with strut-and-tie models and sectional models near the transition between deep and slender beams. Shear test data from a largescale experimental program and the literature (179 total tests) were analyzed. Inappropriately large discrepancies in shear strength calculated using the AASHTO LRFD (2008) strut-and-tie model and sectional shear provisions were found when the shear span-to-depth (a/d) ratio was near 2. The discrepancies were largely due to overly-conservative estimates of strength calculated with the strut-and-tie model provisions in AASHTO LRFD (2008). The discrepancies were greatly reduced with the use of strut-and-tie model provisions developed in this study that were largely based on fib (1999) recommendations.
