Repeated-load tests were carried out on 18 sintered-fly-ash lightweight concrete deep beams, with the aims of (a) comparing the relative effectiveness of three types of web reinforcement for deep beams under repeated loading, and (b) investigating whether the various static shear strength formulas proposed for deep beams could be applied where the beams had a repeated-load history. It was found that inclined web reinforcement was the best type of web reinforcement and that de Paivia and Siess's static shear formula gave the best results.
