Caracterização de segmentos de túneis fabricados com concreto reforçado com fibras
(2015)
Text en actes de congrés
Accés restringit per política de l'editorialA construção de túneis tem grande importância em cidades superpopulosas como é o caso de São Paulo, devido às suas grandes demandas de infraestrutura. Neste sentido, o sistema de escavação mecanizada (TBM) é uma alternativa ... -
Design of FRC tunnel segments considering the ductility requirements of the MC-2010: application to the Barcelona Metro Line 9
(American Concrete Institute (ACI), 2014)
Text en actes de congrés
Accés restringit per política de l'editorialThere are many advantages when using FRC in the manufacturing of segmental linings of tunnels built by means of a Tunnel Boring Machine (TBM). The use of steel fibre reinforced concrete (SFRC) improves, on the one hand, ... -
Design of FRC tunnel segments considering the ductility requirements of the Model Code 2010
(2015-03)
Article
Accés obertFibre reinforced concrete (FRC) is used to improve the mechanical response of precast segments for tunnels. The structural use of the material has been regulated by national codes and, recently, by the Model Code 2010 (MC ... -
Design procedure and experimental study on fibre reinforced concrete segmental rings for vertical shafts
(Elsevier, 2016-02)
Article
Accés obertStructural fibres are used to replace partially or totally the passive reinforcement in precast concrete segments for tunnel linings constructed with TBM, showing several advantages. Fibre reinforced concrete (FRC) could ... -
Double-punch test of fiber-reinforced concrete: effect of specimen origin and size
(2015-03)
Article
Accés restringit per política de l'editorialOne of the main advantages of the Barcelona test is that the properties of fiber-reinforced concrete (FRC) can be determined by using cylindrical specimens, thereby permitting the use of cores to control the quality of ... -
Estudio experimental de la adherencia de mallas de fibras vegetales en compuestos Fabric Reinforced Cementitious Matrix
(Universitat Politècnica de Catalunya, 2019-06)
Treball Final de Grau
Accés obertEl FRCM (Fabric Reinforced Cementitous Matrix), también conocido como TRM (Textile-Reinforced Matrix) es un compuesto muy prometedor para ser utilizado en refuerzo de estructuras antiguas o dañadas por el paso del tiempo. ... -
Influence of fiber orientation on flexural-based design of steel fiber-reinforced concrete slabs: experimental and numerical program
(John Wiley & sons, 2024-03-04)
Article
Accés obertSteel fiber-reinforced concrete (SFRC) has proven to be a suitable structural material for constructing elevated flat slabs, and several existing office and residential buildings, in which SFRC was used for these components, ... -
