Debonding of vegetal FRCM from concrete beams subjected to bending loads
(2022-04-07)
Article
Open AccessThe increasing need of society to develop more sustainable and renewable materials has made vegetal fibers an interesting potential substitute for synthetic fibers in strengthening systems, due to their considerable strength ... -
Performance of hemp-FRCM-strengthened beam subjected to cyclic loads
(2022-03-03)
Article
Open AccessFabric-reinforced cementitious matrix (FRCM) composites are materials that are usually applied to strengthen existing structures. In this study, a hemp mesh coated with epoxy was manufactured and combined with a cementitious ... -
Piezoelectric elements subjected to low frequency excitation. Empirical determination of stress and frequency influence on piezoelectric parameters
(Springer Nature, 2022-08)
Article
Open AccessDesigning optimum energy harvesting devices is the aim of several developments based on numerical or analytical studies of different piezoelectric configurations that usually consider constant piezoelectric properties. ... -
Bending behaviour of sandwich panels of vegetal fabric reinforced cementitious matrix: experimental test and numerical simulation
(2022-07-18)
Article
Open AccessSandwich panels represent a lightweight solution with additional properties as insulation compared to traditional solutions used for building enclosures. In this study, a technology based on vegetal FRCM (fabric reinforced ... -
Characterizing the structural behavior of FRP profiles—FRCM hybrid superficial elements: experimental and numerical studies
(Multidisciplinary Digital Publishing Institute (MDPI), 2022-03)
Article
Open AccessComposite materials have been increasingly used to produce hybrid structures together with concrete. This system is commonly applied to bridges and roof structures. The main idea of the current research was to extend this ... -
Experimental and numerical study of adhesively and bolted connections of pultruded GFRP I-shape profiles
(Multidisciplinary Digital Publishing Institute (MDPI), 2022-03)
Article
Open AccessRecent developments indicate that the application of pultruded FRP profiles has been continuously growing in the construction industry. Generating more complex structures composed of pultruded FRP profiles requires joining ... -
Numerical simulation of masonry walls strengthened with vegetal fabric reinforced cementitious matrix (FRCM) composites and subjected to cyclic loads
(Elsevier, 2022-01)
Article
Open AccessThe growing concern for the preservation of old buildings and the wide use of masonry in the construction of civil works has led to a great development of specific techniques to strengthen masonry structures. FRCM (fabric ... -
Experimental comparison of two testing setups for characterizing the shear mechanical properties of masonry
(Elsevier, 2021-09-08)
Article
Open AccessThe prediction of the structural capacity of masonry buildings against lateral loads requires an accurate characterization of the masonry strength and the general response under shear stresses. The experimental determination ... -
Experimental testing of a composite structural system using tile vaults as integrated formwork for reinforced concrete
(Elsevier, 2021-09-20)
Article
Open AccessTile vaults are unreinforced masonry structures made of thin bricks (tiles) and fast-setting mortar that can be constructed without the need of a formwork, except at the boundaries, making them inherently economic. Their ... -
Experimental and numerical study of shear interface response of hybrid thin CFRP–concrete slabs
(Multidisciplinary Digital Publishing Institute (MDPI), 2021-09-09)
Article
Open AccessHybrid slabs made of carbon-fiber-reinforced polymer (CFRP) and concrete provide a solution that takes advantage of the strength properties of both materials. The performance of the system strongly depends on the CFRP–concrete ... -
Flexible fiber fabric for FRP–concrete connection of thin hybrid slabs
(Multidisciplinary Digital Publishing Institute (MDPI), 2021-08-26)
Article
Open AccessIn order to combat corrosion issues, several studies on progressively replacing steel reinforcement elements with composite ones have been conducted in recent years. Hybrid steel– concrete thin slabs in which the steel ... -
Analytical approach and numerical simulation of reinforced concrete beams strengthened with different frcm systems
(Multidisciplinary Digital Publishing Institute (MDPI), 2021-04-02)
Article
Open AccessFabric-reinforced cementitious matrices (FRCMs) are a novel composite material for strengthening structures. Fabric contributes to tying cross-sections under tensile stress. The complexity of the interfaces between the ...
