This report contains the results of a study to examine the contribution made to the shear capacity of reinforced concrete beams of shear reinforcement that does not comply with the detailing requirements of the UK bridge design code. The main goal was to determine whether it is possible to relax the detailing requirements and remove any unnecessary conservatism that might exist in BD 44. The report contains the results of a literature review as well as the conclusions of a testing programme to investigate different details. These details include wide or varying spacing of links, links with less than the nominal area, and links not surrounding the main tension steel. The report discusses areas where relaxations may be possible, drawing on the conclusions of the literature review, the test programme and the analysis.
