  Load-bearing and Bonding Behavior of Hybrid Concrete Tunnel Lining Segments

  Abstract: Concrete damages occurring frequently in the peripheral zones of segments cannot be prevented by using conventional steel reinforcement due to the adherence of minimum concrete cover. Based upon this fact, a new concept has been developed to manufacture hybrid concrete segments with a so-called “fresh on solid” production procedure. In this procedure, tailor-cut precast components made of...

  Steel fiber-reinforced concrete for precast tunnel lining segments

  Abstract: Precast tunnel lining segments are often subjected to critical impact and concentrated loads especially during the construction stage. The peripheral regions of segments, such as edges and corners, are usually exposed to significantly higher stresses than the interior. Under such high stress concentrations, concrete damages in the form of cracking and spalling are very likely to occur in these...
