Model to simulate the behaviour of RC beams shear strengthened with ETS bars
Barros, Joaquim A. O.; Breveglieri, Matteo; Gouveia, A. Ventura; Dalfré, Gláucia; Aprile, AlessandraTo predict correctly the deformational and the cracking behavior of reinforced concrete elements failing in shear using a smeared crack approach, the strategy adopted to simulate the crack shear stress transfer is crucial. For this purpose, several strategies for modeling the fracture mode II were implemented in a smeared crack model already existing in the FEM-based computer program, FEMIX. Special development...
The contribution of embedded through-section bars for the shear resistance of RC
Dalfré, Gláucia; Barros, Joaquim A. O.; Breveglieri, Matteo; Aprile, AlessandraIn a recent experimental program, the performance of a novel shear strengthening technique, designated by Embedded Through-Section (ETS), was appraised by performing a series of beam bending tests composed of eight reinforced concrete (RC) beams. According to this strengthening technique, holes are opened through the beam’s section, with the desired inclinations, and bars are introduced into these holes an...

Dalfré, Gláucia; Barros, Joaquim A. O.; Breveglieri, Matteo; Aprile, AlessandraOs programas experimentais para o reforço à flexão de estruturas de betão armado (BA) segundo a técnica NSM (Near Surface Mounted, em língua inglesa) com laminados de CFRP (Carbon Fiber Reinforced Polymer, em língua inglesa) são, em geral, realizados com vigas simplesmente apoiadas. Deste modo, há uma carência de estudos experimentais e teóricos sobre a capacidade de redistribuição de momentos em elementos ...
Assessment of the effectiveness of NSM-CFRP flexural strengthening configuratio...
Breveglieri, Matteo; Barros, Joaquim A. O.; Dalfré, Gláucia; Aprile, AlessandraThe experimental programs for the flexural strengthening of reinforced concrete (RC) structures using the Near Surface Mounted (NSM) technique with Fiber Reinforced Polymer (FRP) laminates were, in general, conducted with simply supported beams. Therefore, there is a lack of experimental and theoretical studies on the moment redistribution of statically indeterminate RC elements strengthened with NSM technique....
