Popis: Radial joints are defined as the contact part between precast segments in each ring of mechanical excavated tunnel lining. The behavior of flat radial joints without connectors is investigated in this paper through full-scale experimental tests on fiber reinforced concrete elements without any traditional reinforcement. The tests were performed by imposing a joint opening, as typical can occur when higher level of ovalization in the lining are required. The results showed the effect of concrete crushing as well as the bursting phenomena. Finally, an analytical interpretation of the behavior is presented, providing useful information that can support the design of this type of joints.
