[EN] The shear strength of elements reinforced by fibres is predicted by Codees using formulations generally developed from a limited set of test results.
[EN] Shear behaviour in reinforced concrete (RC) elements can improve with an adequate amount of fibres. Research has recently determined how fibres affect shear strength, but has barely focused on macro synthetic ...

[EN] Heuristically known at least since the first half of XIX century, the self-healing capacity of cement-based materials has been receiving keen attention from the civil engineering community worldwide in the last decade. ...
Hollow core slabs (HCS) are usually precast by extrusion and it is not easy to place stirrups; thus, it is difficult to guarantee shear resistance in some cases. This paper describes an experience using fiber-reinforced ...
Steel fibers are known to improve shear behavior. The Design Codes (Eurocode 2 (EC2), Spanish EHE-08, Model Code 2010 and RILEM approach) have developed formulas to calculate the fiber contribution to shear, mainly focused ...
[EN] A detailed methodology to perform the so-called push-off test in precracked concrete specimens is presented. The test is performed with the specimen confined in 2 stages (precracking and push-off) to control crack ...
[ES] El presente artículo analiza la repetitividad de la capacidad autorreparante del hormigón reforzado con fibras. Para llevar a cabo dicha investigación se han fabricado dos tipos de hormigón cuya única diferencia ha ...
Even after many years of in-depth research the shear behavior of concrete structures is still a subject for debate. Current Design Codes need to be adapted to new materials and production methods. This paper discusses some ...
