Abstract:

The importance of the analysis of circular columns to accurately predict their ultimate confined ; capacity under shear-flexure-axial force interaction domain is recognized in light of the extreme load event ; imposed by the current American Association of State Highway and Transportation Officials (AASHTO) ; Load and Resistance Factor Design (LRFD) Bridge Construction Specifications (AASHTO, 2014). In this ; study, various procedures for computing shear strength are reviewed. Then, the current procedure adopted by ; AASHTO LRFD specifications, based on the Simplified Modified Compression Field Theory, is evaluated ; for non-prestressed circular concrete bridge piers. This evaluation is benchmarked against experimental data ; available in the literature, and against Response 2000 freeware program that depicts interaction diagrams ; based on AASHTO (1999) LRFD requirements. Differences in results are discussed and future ; improvements are proposed. A new approach is presented to improve the accuracy of AASHTO LRFD ; calculations. The main parameters that control the cross section shear strength are discussed based on the ; experimental results and comparisons.
