✦ Synopsis

In a previous paper entitled &&Damping identi"cation in multi-degree-of-freedom (m.d.o.f.) systems via wavelet-logarithmic decrement*Part 1: theory'', a wavelet-logarithmic decrement formula was established to estimate damping in multi-degree-of-freedom systems from time-domain responses. Numerical validation was then investigated using the dynamic response of exact single-degree-of-freedom systems that were arti"cially perturbed with a Gaussian noise. Part 2 is now dedicated to the application of the wavelet procedure to identify the damping of in situ dynamic responses of a civil engineering building excited with both harmonic and shock testings.
