<p>This paper deals with a shotcrete lining with steel sets. The nonlinear analyses of a reinforced shotcrete lining are performed by using fiber beam-column element, which is a forced based element on the Euler-Bernoulli beam theory. The constitutive model ...

<p>This paper describes the activities of the International Tunnelling and Underground Space Association (ITA) Working Group 12 on Sprayed Concrete Use. The Working Group has carried out tasks with the purpose of promoting information exchange between National ...

<p>The Western Australian School of Mines (WASM) has developed a facility for the static testing of full scale ground support elements. The test facility consists of several stiff steel frames used to support the sample and a screw feed jack is used to load ...

<p>The paper deals with the concrete lining behaviour at Serviceability Limit State (SLS) in order to evaluate the advantages that result from an optimized reinforcement based on the combination of rebars and fibers with respect to the crack behaviour of segmental ...

<p>New procedures to design cast-in-situ steel fiber reinforced concrete (SFRC) tunnel linings are briefly presented in this paper. The ductile behavior at ultimate limit stage of such cement-based structures is ensured by a suitable amount of steel fibers ...

The paper addresses precast tunnel segments for the Line T02 of Saronno-Malpensa railway (Italy). After the experimental determination of the material properties, the structural behavior of the lining is simulated with FE analyses based on Non Linear Fracture ...

<p>The structural applications of Steel Fiber Reinforced Concrete (SFRC) have recently been increasing due to the improvement of material properties, such as in the material toughness under tension and durability. However, because the behavior of such structures ...

<p>Given the high deformability requirements of shotcrete in repair, rehabilitation, slope stabilization, ground support, and other applications, the use of fibers in shotcrete is growing. Growing also are challenges surrounding the use of fibers in shotcrete ...

<p>The purpose of this paper is to describe some applications where FRS has produced satisfactory results, with reasonable costs and often with a significant reduction in total construction time. The use of shotcrete for slope and rock stabilization has increased ...

The study involved a laboratory and a theoretical analysis designed to understand whether the use of short fibers increases the shear strength of fissured clays. The laboratory experiments involved the direct shear testing of reinforced and unreinforced clay ...
