Abstract:
Combined reinforcement, a combination of traditional reinforcement and steel fiber reinforcement, has become an established construction method for joint free industrial floors and heavy raft foundations. Besides the positive contribution to the flexural, the shear and punching capacity, combined reinforcement has a big impact on the limitation of crack widths. The post crack tensile strength of steel fiber reinforced concrete can be taken into account for serviceability as well as for ultimate limit state. Structures which were built with combined reinforcement can be found all over the world. Some of them will be presented in this paper, giving insight information why combined reinforcement was chosen.
