Yield displacement of slender cantilever RC walls as a function of the seismic demand features

The yield displacement is a relevant parameter to design slender cantilever RC walls under seismic actions. If the wall expected undergo inelastic excursions, then used estimate ductility demands, which are in turn boundary elements (confinement reinforcing). In last years, expressions have been proposed several studies; many of them resorting models with concentrated inelasticity. Results obtained these could be unrepresentative phenomenon studied, due assumption that has elastic behaviour and constant stiffness above critical section; evidence shows flexural varies during dynamic response. Independently model used, most studies consider pushover analysis different lateral load patterns (e.g. triangular or uniform), assuming nature demand. this work, parametric study for presented. results were from nonlinear response history analyses (NRHA) set walls, representative real buildings. To carry out NRHA, natural artificial records features used. Additionally, aspect ratio, height, thickness longitudinal reinforcement considered; modelled unidirectional fibres. final discussion focused on influence higher mode effects its variability, order provide useful simple recommendations.
