This article describes an experimental program developed to study the influence of longitudinal prestress on the behaviour of high-strength concrete hollow beams under pure torsion. The pre-cracking, the post-cracking and the ultimate behaviour are analysed. Three tests were carried out on large hollow high-strength concrete beams with similar concrete strength. The variable studied was the level of longitudinal uniform prestress. Some important conclusions on different aspects of the beams’ behaviour are presented. These conclusions, considered important for the design of box bridges, include the influence of the level of prestress in the cracking and ultimate behaviour.

Maximum Crack

The effect of volume fraction of steel fiber and the strength of reinforcement on the maximum crack width of steel fiber reinforced high-strength concrete beams was analyzed based on experimental results. In addition, the formula to calculate the maximum crack width of steel fiber-reinforced high-strength concrete beams was established.
