Additional fire exposure time for the effect of spalling in reinforced concrete columns

Peña, D. L.; Ibáñez, Carmen; ALBERO GABARDA, VICENTE; Hospitaler Pérez, Antonio (Springer-Verlag, 2023-04-21)

[EN] Concrete exposed to fire can experience spalling when the pore pressure increases due to water evaporation resulting in damage to part of the concrete cross-section which causes the loss of the initial cross-sectional ...
Arch Beam column imperfection

Agüero Ramón Llin, Antonio (2024-06-25)

La siguiente aplicación permite determinar los movimientos y esfuerzos dentro de y fuera del plano, y la capacidad resistente de las arcos comprimidos y flectados con sección en doble te, susceptibles de pandear en el plano ...
Composite column tests - database and comparison with Eurocode 4

Goode, Charles (Editorial Universitat Politècnica de València, 2018-06-05)

[EN] The database of 1819 tests on concrete-filled steel tube columns was reported in 2008 [1,2] and covered all tests traced by the author up to 2007. This paper reports on 473 more tests carried out by 26 researchers ...
Efecto de la fertilización fosfórica sobre la lixiviación y mineralización del herbicida glifosato en suelos de cultivo de arroz

Muñoz Molina, Alejandro (Universitat Politècnica de València, 2018-05-21)

[ES] Glifosato es un herbicida no selectivo, que actúa inhibiendo la ruta de acción del ácido shikimico en plantas. En el suelo, esta molécula se inmoviliza debido a que se adsorbe fuertemente a coloides del suelo, en ...
Effective flexural stiffness of slender reinforced concrete columns under axial forces and biaxial bending

Bonet Senach, José Luís; Romero, Manuel L.; Miguel Sosa, Pedro (Elsevier, 2011-03)

Most of the design codes (ACI-318-2008 and Euro Code-2-2004) propose the moment magnifier method in order to take into account the second order effect to design slender reinforced concrete columns. The accuracy of this ...
Estudio del comportamiento termo-mecánico seccional de columnas rectangulares de hormigón armado sometidas a la acción del fuego. Flexo-compresión recta y esviada

Peña Mansilla, David Leonardo (Universitat Politècnica de València, 2018-10-16)

En el presente trabajo final de máster (TFM), se estudiará el comportamiento de columnas de sección rectangular de hormigón armado ante la acción accidental del fuego. Específicamente se estudiará este tipo de sección y ...
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 ...
Non-linear analysis of rheological effects in slender composite columns

Fenollosa Forner, Ernesto Jesús; Cabrera Fausto, Ivan; Almerich Chulia, Ana Isabel (Trans Tech Publications, 2014-07-04)

[EN] A thorough analysis of slender columns under axial force and bending moment requires second order effects assessment. Concrete s creep is one of the factors that increase lateral displacements of the bar in the long ...
Non-linear Analysis of Slender High Strength Concrete Column

Fenollosa Forner, Ernesto Jesús; Cabrera Fausto, Ivan; Llopis-Pulido, Veronica; Alonso Durá, Adolfo (Bentham Science, 2019-07)

[EN] This article shows the influence of axial force eccentricity on high strength concrete columns design. The behavior of columns made of normal, middle and high strength concrete with slenderness values between 20 and ...
Simplified numerical modelling of rectangular concrete-filled steel columns, beams and beam-columns

Tao, Zhong; Katwal, Utsab; Hassan, Kamrul; Wang, Wen-Da (Editorial Universitat Politècnica de València, 2018-06-05)

[EN] Because of its computational efficiency, simplified numerical modelling is the preferred method to simulate structural frames for routine design. As for concrete-filled steel tubular (CFST) columns, fibre beam element ...
Simplified proposal for the temperature field of steel-reinforced CFST columns exposed to fire

Medall-Martos, David; Espinós Capilla, Ana; ALBERO GABARDA, VICENTE; Romero, Manuel L. (Elsevier, 2022-12-15)

[EN] Concrete-filled steel tubular (CFST) columns are composite sections that may contribute to reduce the envi-ronmental impact in construction through a more efficient use of resources. By embedding a steel profile inside ...
Slenderness limit of the weak axis in the design of rectangular reinforced concrete non-sway columns

Cortés Moreno, Eduardo; Bonet Senach, José Luís; Romero, Manuel L.; Miguel Sosa, Pedro (Elsevier, 2011-02-03)

Most design codes (Model Code 90, ACI-318-2008 and Eurocode-2-2004) suggest that the effect of a geometrical imperfection ought to be taken into account in the most unfavorable direction when designing slender reinforced ...
