BEHAVIOR OF REINFORCED-CONCRETE-FRAMED SHEAR WALLS

Based on equilibrium and compatibility conditions, as well as a soften ed stress-strain relationship for normal strength concrete, a truss mo del theory was derived to predict the strength and behavior of low-ris e reinforced-concrete-framed shear walls. A new softened stress-strain relationship was recently proposed for normal and high-strength concr ete. Both the softening models of concrete are based on the shear pane ls under static loads. The purpose of this paper is twofold: (1) to ex amine the applicability of both the softening models to low-rise frame d shear walls; (2) to determine the effect of dynamic shear forces wit h low frequency (0.2 Hz) on the behavior of such walls.
