Abstract

The introduction of the Eurocodes for Concrete design will alter the way that shear design is approached for concrete structures. The Eurocodes have adopted the variable angle truss model for shear, a more theoretically consistent approach than that found in the British Standards. The model is confidently applied to rectangular sections, but its applicability to irregular sections is less clear. In particular, the behaviour of circular concrete sections such as those often used as bridge piers is not well defined. A requirement for design guidance on this topic has been recognised by key BSI Committees and this dissertation is intended to help shape and inform future UK design practice.This dissertation provides a state of the art review of shear design in concrete, followed by detailed analysis of the Eurocode approach. Using both experimental and theoretical data, the Eurocode variable angle truss model for shear design is assessed and extended to circular columns. Previously published test results and guidance are reviewed in the context of the introduction of the Eurocodes and from this new guidance for designers is determined
