Numerical simulation of transparent glass-GFRP composite beams using smeared cr...
Valarinho, Luís; Sena-Cruz, José; Correia, João R.; Branco, Fernando A.This paper describes results of experimental and numerical investigations about the structural behaviour of composite beams made of annealed glass panes and GFRP pultruded profiles. A brief description of flexural tests previously carried out on glass and glass-GFRP composite beams is first presented. The second part of this paper describes the numerical simulation of a rectangular glass-GFRP composite beam. Tw...
Experimental investigations on continuous glass-GFRP beams : preliminary nonlin...
Valarinho, Luís; Correia, João R.; Branco, Fernando A.; Sena-Cruz, JoséThis paper describes results of experimental and numerical investigations about the structural behaviour of composite beams made of annealed glass panes and GFRP pultruded profiles. A brief description of flexural tests previously carried out on simply supported glass and glass-GFRP composite beams is first presented. Then, results of flexural tests on two-span glass-GFRP composite beams, bonded with three diff...
Evaluation of the dynamic behavior of a GFRP-SFRSCC hybrid footbridge
Gonilha, José; Correia, João R.; Branco, Fernando A.; Barros, Joaquim A. O.This paper presents results of numerical investigations on the dynamic behaviour of a hybrid footbridge made of glass fiber reinforced polymer (GFRP) pultruded profiles and a steel fibre reinforced self-compacting concrete (SFRSCC) slab. Finite element (FE) models were developed to simulate the dynamic response of the footbridge when subjected to human induced vibrations. Results obtained were compared with req...
Influence of added concrete compressive strength on adhesion to an existing con...
Júlio, Eduardo N. B. S.; Branco, Fernando A. B.; Silva, Vítor D.; Lourenço, Jorge F.An experimental study was performed to evaluate the bond strength between two concrete layers of different ages, considering different mixtures of added concrete, with different strengths. The specimens first had the roughness of the substrate surface increased by sand blasting. Later, the new concrete was added. Afterwards, slant shear tests were performed to quantify the bond strength in shear. These tests in...
Concrete-to-concrete bond strength. Influence of the roughness of the substrate...
Júlio, Eduardo N. B. S.; Branco, Fernando A. B.; Silva, Vítor D.An experimental study was performed to evaluate the bond strength between two concrete layers, for different techniques for increasing the roughness of the substrate surface. In a total of 25 slant shear specimens and 25 pull-off specimens the substrate surface was prepared by wire-brushing; sand-blasting; chipping with a light jackhammer; or were left as-cast against steel formwork. Three months later, the new...
