Análisis de un caso de inestabilidad lateral de un viga de hormigón pretensado de gran luz en fase de izado
(2018-09)
Article
Open AccessLas mejoras tecnológicas de la prefabricación con hormigón han hecho competitivo el uso de vigas prefabricadas de luces cada vez mayores en comparación con otras alternativas. Sin embargo, el peso de las vigas es limitante ... -
Application study of embedded Rayleigh based Distributed Optical Fiber Sensors in concrete beams
(Elsevier, 2017)
Conference report
Open AccessIn this work, an experiment on two small concrete beams is described where Rayleigh based distributed optical fiber sensors (DOFS) are implemented together with traditional electrical strain gauges for the monitoring of ... -
Bending performance of concrete beams strengthened with textile reinforced mortar TRM
(2014)
Article
Open AccessThis work presents a method of strengthening concrete structures based on textiles of high strength and mortars. The combination of textiles and mortars produces a new composite material with cementitious matrix. This ... -

Estudio numérico del efecto tamaño en la cabeza de compresión de vigas esbeltas de hormigón armado sin refuerzo transversal mediante el método de elementos finitos
(Universitat Politècnica de Catalunya, 2017-09)
Master thesis
Open AccessLa resistencia a cortante de estructuras de hormigón armado se ve afectada por el tamaño. Dado que la contribución de la cabeza de compresión a la resistencia a cortante es significativa, conviene cuantificarla con precisión, ... -
Experimental study on the fire resistance of beam string structures
(Universitat Politècnica de Catalunya, 2017-05)
Master thesis
Restricted access - author's decisionThe research will focus on the structural behavior of beam string structures (BSS) at elevated temperatures, for which a series of fire tests will be carried out in fire test furnace. BSS specimens will be exposed to fire ... -
Flexural behavior of steel concrete composite beam with web openings and strengthened by CFRP laminates
(CIMNE, 2015)
Conference lecture
Open AccessThe present study is aiming to investigate the structural behavior of simply supported composite beams in which a concrete slab is connected withsteel beam by headed stud shear connector or by using epoxy layer as a shear ... -

One-way shear design method based on a multi-action model
(2017-09)
Article
Restricted access - publisher's policyIt is widely known that the shear strength of a reinforced concrete (RC) or prestressed concrete (PC) beam results from the interaction of different resisting actions. Thus, available simplified shear models emphasize ... -

Shear strength of beams with loads near the supports
(Universitat Politècnica de Catalunya, 2015-05-08)
Master thesis
Open AccessIn reinforced concrete beams subjected to concentrated loads, the shear resisted increases considerably as the loads approach to the support. There is not a consensus in the current codes of practice about any simple ... -
Simulations of fracture in concrete beams under bending using a continuum and discrete approach
(CIMNE, 2015)
Conference lecture
Open AccessThe paper describes two-dimensional meso-scale results of fracture in notched concrete beams under bending. Concrete was modelled as a random heterogeneous 4-phase material composed of aggregate particles, cement matrix, ... -
