The present work describes the analysis of a long and jointless concrete foundation reinforced with conventional steel meshes and discrete polypropylene fibers. A thermo-mechanical nonlinear transient simulation is performed to assess the cracking risk and magnitude of the fiber reinforced concrete (FRC) due to the heat development generated from t...

This paper presents a new pre-fabricated lightweight slab system where the relatively high post-cracking tensile capacity of steel fibre reinforced concrete (SFRC) is combined with the high ductility and tensile strength of optimized shape profiles made by cold formed steel sheets for a synergetic result in terms of structural performance. The SFRC...

A exposição de estruturas de betão a temperaturas elevadas, como no caso de incêndio, conduz, entre outros, a uma degradação das propriedades mecânicas do material. Dependendo da temperatura e do tempo de exposição, esta ocorrência acidental potencia a ocorrência de fissuração e destacamento do betão – spalling (por vezes de forma explosiva), poden...

The present work describes an integrated approach that leads to the development of a new model capable of describing the tensile behavior (mode I) of fiber reinforced concrete (FRC), considering the orientation of the fibers, the fibers segregation along the cross-section of the FRC members and the pullout constitutive model of each fiber bridging...

Within the scope of the “NG_TPfib” R&D project, Exporplás and CiviTest have, in the recent past, developed a new typology of polypropylene fibers for the production of urban furniture of high durability by eliminating conventional steel reinforcements susceptive to corrosion. This reinforcement replacement strategy also allows the development of li...
