Design procedure for precast fibre‐reinforced concrete segments in tunnel lining construction

Abstract: A procedure for the design of precast tunnel segments for mechanical excavated tunnel lining in fiber reinforced concrete, without any traditional steel reinforcement, is presented herein. Both assisted by test procedure for particular loading situation is also proposed. Finally, a case study related to a precast steel fiber reinforced concrete segment is analysed in order to clarify the procedure and to show practically how to define the actions and to evaluate the interaction envelopes.

“…The empirical models are further validated using data from a total of 39 bending tests conducted by Soetens and Matthys, Amin et al, and Grimaldi et al on SFRC with single hook steel fibers. With several researchers requiring the results from bending tests to establish the constitutive relation for SFRC in tension, the proposed empirical equations for the residual flexural strengths are useful for determining the same without the effort of conducting prism tests.…”

“…At the same time the material of station is reinforced concrete with following data: the modulus of elasticity and density of reinforced concrete structure are 31500 MPa, 0.025 MN/m 3 , the density and friction angle of soil are 0.018 MN/m 3 , 26°. For physical modeling of station we are used the shell triangular finite element with 5 degrees of freedom at each node [13][14][15].…”

“…Studies in the literature reveal that there is not a clear consensus to specify and researchers use different criteria to determine its value [16]. However, the MC2010 suggests considering to be equal to the depth of the structural element to be designed, a criteria that has been used and validated by several authors [17,18].…”
