Bond behavior of near-surface mounted CFRP laminate strips under monotonic and ...
Sena-Cruz, José; Barros, Joaquim A. O.; Azevedo, Álvaro F. M.; Gettu, RavindraNear-surface mounted (NSM) carbon fiber reinforced polymer (CFRP) laminate strips are used to increase the load-carrying capacity of concrete structures by inserting them into slits made in the concrete cover of the elements to be strengthened and gluing them to the concrete with an epoxy adhesive. In several cases the NSM technique has substantial advantages when compared with externally bonded laminates. In o...
Comportamento da ligação de laminados de CFRP inseridos no betão sob acções cíc...
Sena-Cruz, José; Barros, Joaquim A. O.; Gettu, RavindraCom o objectivo de avaliar a influência do comprimento de aderência e da história do carregamento no comportamento da ligação de laminados de fibras de carbono (CFRP) ao betão, foram efectuadas campanhas de ensaios com três comprimentos de aderência distintos e diferentes tipos de história de carga. O CFRP é inserido em ranhuras efectuadas no betão e é fixo ao betão por intermédio de um adesivo epoxy. No presen...
Material nonlinear analysis of steel fibre reinforced concrete beams failing in...
Barros, Joaquim A. O.; Gettu, Ravindra; Barragán, BryanExperimental research has pointed out that fibre reinforcement gives valuable contribution for the shear strength of concrete beams. To obtain data to check the validity of the formulation proposed by RILEM TC 162-TDF for the evaluation of the fibres contribution for the concrete shear strength, sets of concrete beams were tested experimentally. To simulate the behaviour of this kind of structures, a computatio...
On the experimental study of the interface between a fiber composite lamina and...
Gettu, Ravindra; Sena-Cruz, José; Barros, Joaquim A. O.; Santos, António Carlos dos; Bittencourt, TúlioIn order to properly evaluate the failure characteristics and the strength of the bond between concrete and a fiber reinforced polymer (FRP) lamina, it is necessary to study the shear failure of the corresponding interface under different loading conditions. Two test configurations that permit such characterization are discussed here. The first is applicable to thin surface bonded laminas, and the test is perfo...
