RESONANCE CAPACITY CRITERION FOR EVALUATION OF THE ASEISMIC CAPACITY OF REINFORCED CONCRETE STRUCTURES

It is proposed that the aseismic capacity of a reinforced concrete structure is the steady state resonance capacity for an idealized one mass model of that structure subjected to a sinusoidal forced vibration. That resonance capacity is determined using the known characteristics of the hysteresis loops and the stability in strength with cycling of typical reinforced concrete elements. For this evaluation reinforced concrete members are classified, according to their modes of deformation and failure under monotonic loading, into three types of aseismic elements: Long columns, short columns, and shear walls. Structures are divided into two types: rigid and flexible. A diagram is developed showing the interaction surface in three dimensional space between shear force amplitude, equivalent viscous damping and the natural period of vibration. That interaction surface is shown to represent a reasonable basis for estimating the aseismic safety of reinforced concrete structures.
