EFFECT OF CONCRETE STRENGTHS ON DYNAMIC-RESPONSE OF FRAMED SHEARWALLS

To perform dynamic response analysis of reinforced concrete framed she arwalls, the following three parts are required: (1) the truss model t heory for the primary curves of framed shearwalls; (2) the analytical model of the hysteresis loops which describe the behaviour of the wall s under repeated loading and unloading; and (3) the dynamic model used for dynamic analysis, The combination and implementation of these thr ee components form a useful tool for the dynamic analysis of such wall s, Using this tool, numerical experimentations are executed to study t he effect of material properties on the dynamic response of such walls , It was found that higher concrete strength has greater ductility fac tor, less ductility demand and less energy index.
