Analysis of the shear strength mechanism of slender precast concrete beams with cast-in-place slab and web reinforcement

Rueda-García, Lisbel; Bonet Senach, José Luís; Miguel Sosa, Pedro; Fernández Prada, Miguel Ángel (Elsevier, 2021-11-01)

[EN] Precast concrete beams with cast-in-place slabs on top, namely concrete composite beams are frequently used for building concrete bridge decks. In designs, the contribution of cast-in-place slabs to shear strength ...
Comparison of macrosynthetic and steel FRC shear-critical beams with similar residual flexure tensile strengths

Ortiz-Navas, Francisco; Navarro-Gregori, Juan; Leiva, Gabriel; Serna Ros, Pedro (Techno-Press, 2020-11-25)

Experimental analysis of the shear resistance of precast concrete T-beams with a top cast-in-place slab

Rueda-García, Lisbel; Bonet Senach, José Luís; Miguel Sosa, Pedro; Fernández Prada, Miguel Ángel (Elsevier, 2023-09-15)

[EN] Precast concrete T-beams with a cast-in-place slab on top are structural elements that are often employed in composite construction. Despite their widespread use, some aspects of their structural behaviour upon shear ...
Experimental Assessment of the Shear Resistant Behaviour of Precast Concrete Beams with Top Cast-in-Place Concrete Slab

Rueda García, Lisbel (Universitat Politècnica de València, 2022-06-27)

[ES] La construcción con elementos prefabricados de hormigón es un sector en alza por la aceleración del proceso constructivo, el ahorro de costes derivados de la obra in situ y la mejora de la calidad y acabados, entre ...
Experimental study of shear strength in continuous reinforced concrete beams with and without shear reinforcement

Monserrat López, Andrea; Miguel Sosa, Pedro; Bonet Senach, José Luís; Fernández Prada, Miguel Ángel (Elsevier, 2020-10-01)

[EN] Shear strength of reinforced concrete beams has been extensively studied by many experimental campaigns conducted on simply supported beams. This situation has led to implement empirical design formulations in codes ...
Experimental study on the shear strength of reinforced concrete composite T-shaped beams with web reinforcement

Rueda-García, Lisbel; Bonet Senach, José Luís; Miguel Sosa, Pedro; Fernández Prada, Miguel Ángel (Elsevier, 2022-03-15)

[EN] The current increasing use of precast concrete elements and cast-in-place concrete slabs, namely concrete composite elements, in construction requires a better understanding of their behaviour in shear. In this work, ...
Experimental tests of slender reinforced concrete columns under combined axial load and lateral force

BARRERA PUERTO, ANGELA; Bonet Senach, José Luís; Romero, Manuel L.; Miguel Sosa, Pedro (Elsevier, 2011-12)

The use of high strength concrete (HSC) in columns has become more frequent since a substantial reduction of the cross-section is obtained, meaning that slenderness increases for the same axial load and length, producing ...
Feasibility of iron-based shape memory alloy strips for shear strengthening of damaged RC beams promoting the formation of plastic hinges

Traver-Abella, Celia; Ruiz Pinilla, Joaquín Guillermo; Monserrat-Lopez, Andrea; Montoya-Coronado, Luis A.; Miguel Sosa, Pedro; Ribas, Carlos; Cladera, Antoni; Bonet Senach, José Luís (Elsevier, 2023-10-19)

[EN] This research focuses on the proof of concept of the feasibility of iron-based shape memory alloys strips (Fe-SMA) to strengthen damaged structures by promoting the yielding of longitudinal reinforcement. For this ...
Influence of the plastic hinge rotations on shear strength in continuous reinforced concrete beams with shear reinforcement

Monserrat López, Andrea; Miguel Sosa, Pedro; Bonet Senach, José Luís; Fernández Prada, Miguel Ángel (Elsevier, 2020-03-15)

[EN] Continuous reinforced concrete (RC) beams may develop significant plastic rotations to enable the redistribution of bending moments. These rotations occur at plastic hinges, which are subject to high shear forces. The ...
Influencia del ciclo de curado en las características a cizalladura de composites de alto gramaje con resinas vinil-uretano
