Softening of reinforced concrete sections at advanced curvatures in flexure is taken into account in collapse load analysis of frames. The analysis employs a trilinear elastic-plastic-softening approximation to real moment-curvature curves, and elastic unloading and reloading from the softening curve is assumed. Formulas for hinge length in reinfor...

... Algunas aproximaciones modelan el comportamiento inelástico mediante resortes en los extremos de un elemento viga -columna, cuyo comportamiento es elástico lineal (Giberson, 1967;Homoud, 1991;Chan y Chui, 1997, entre otros). Otras aproximaciones subdividen el elemento viga -columna en subdominios, en los que el comportamiento inelástico se modela en subdominios con o sin longitud (Darvall y Mendis, 1985;Powell y Chen, 1986, entre otros). En plasticidad distribuida, los elementos viga -columna se han desarrollado mediante formulaciones basadas en los desplazamientos o en las fuerzas, donde un modelo de fibras o un modelo de plasticidad resultante de esfuerzos, describe el comportamiento en una sección (Chen y Powell, 1982;Spacone et al., 1996;Scott y Fenves, 2006;Feng et al., 2017;Poliotti y Bairán, 2020, entre otros). ...
