Estudio del comportamiento del hormigón armado ante esfuerzos normales y tangentes mediante modelos seccionales de interacción completa

Abstract: Estudio del comportamiento del hormigón armado ante esfuerzos normales y tangentes mediante modelos seccionales de interacción RESUMEN El análisis tradicional de estructuras reticulares se basa en las teorías clásicas de vigas cuyas hipótesis de partida implican la única existencia de tensiones normales en la sección transversal o, en algunos casos, también tensiones tangenciales con simplificaciones más o menos acertadas. Su aplicación resulta satisfactoria en casos dominados por solicitaciones normales. Exis… Show more

“…Recent investigations have resulted in the development of numerical models that are capable of estimating strength mechanisms under tangential forces and, particularly, shear forces occurring in RC structures, although the formulas for manual calculation of shear stress forces still entail a large empirical content. These highly non-linear forces are characterized by a strong multi-axial tensile deformation mechanism [6][7][8][9][10][11][12] that produces oblique cracking non-parallel to the plane of the main section. The shear strength capacity of a concrete specimen also depends on other factors that are independent of transverse section.…”

“…En cualquier caso, también es cierto que en modelos más refinados, que requieren de un coste computacional elevado, no se acostumbra plantear que toda la resistencia a cortante se deba a las tensiones en la cabeza comprimida, sino que se tienen en cuenta todas las distintas contribuciones a la resistencia a cortante (11).…”

“…Many monitoring activities related to concrete structures rely on the measurement of the change of dynamic properties. Reinforced concrete has a highly nonlinear behaviour, whose response is not always easy to be determined in advance under a combination of loads (6). Cracking is the most usual damaging process that affects such response.…”
