COMPORTAMENTO DE LIGAÇÕES VIGA-PILAR DE CONCRETO PRÉ-MOLDADO UTILIZANDO CONCRETO COM FIBRAS DE AÇO

This paper presents a study of the behavior of grouted dowel partially resistant to bending moment and the behavior of beam-column connection using molded corbels with steel fibers in distinct stages of the column.  This research includes an experimental program conducted at the LE-EESC and a numerical analysis using the software DIANA. These experimental and numerical tests search for to provide analytical models that are able to represent the influence and other parameters in the mechanism of the anchor dowel in concrete with fibers. The aim is also based on the behavior of deformation mechanisms and resistance in the present connection, to evaluate their influence on the overall behavior of the bond offering analytical models for the determination of the bending moment-rotation to consider a semi-rigid connections.
