Abstract

This work presents a new definition of the numerical angular frequency and numerical damping ratio, within the framework of the time integration of second-order differential equations. The standard approach deals with the ability of the numerical schemes to deliver an accurate response in time. It is well suited to the study of the explicit schemes used in fast transient dynamic analysis. The new approach emphasises the capability of the scheme to deliver an accurate resonant response. This complementary frequency viewpoint is helpful in the study of the implicit schemes used in civil engineering applications.
