摘要：

In a previous paper entitled "Damping identification in multi-degree-of-freedom (m.d.o.f) systems via wavelet-logarithmic decrement-Part I. 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 artificially 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.
