Item Round Robin Test for composite-to-brick shear bond characterization(2012-12) Valluzzi, Maria Rosa; Oliveira, Daniel V.; Caratelli, Angelo; Castori, Giulio; Corradi, Marco; De Felice, Gianmarco; Garbin, Enrico; Garcia, David; Garmendia, Leire; Grande, Ernesto; Ianniruberto, Ugo; Kwiecień, Arkadiusz; Leone, Marianovella; Lignola, Gian Piero; Lourenço, Paulo B.; Malena, Marialaura; Micelli, Francesco; Panizza, Matteo; Papanicolaou, Catherine G.; Prota, Andrea; Sacco, Elio; Triantafillou, Thanasis C.; Viskovic, Alberto; Zaja̧c, Boguslaw; Zuccarino, Gina; TRAZABILIDAD CIRCULAR; Tecnalia Research & InnovationThe paper presents the experience of a working group within the RILEM Technical Committee 223-MSC 'Masonry Strengthening with Composite materials', aimed at developing a standardized, reliable procedure for characterizing the bonding mechanism of masonry elements strengthened with composite materials under shear actions. Twelve laboratories from European universities and research centers were involved. Two different set-ups were compared, for single-lap and double-lap shear tests (the latter in two versions). Four kinds of fiber fabrics, i.e., glass, carbon, basalt and steel, were applied with epoxy resins (wet lay-up system) to clay brick units, for a total of 280 monotonic tests. The results provided information regarding the response of externally bonded-to-brick composites in terms of observed failure mechanisms, load capacity, effective transfer length, and bond shear stress-slip behavior. The test results of the 12 laboratories constitute a set of statistically representative data which may conveniently be used for setting appropriate design provisions and guidelines.
