Monitoring structural damage is extremely important for sustaining and preserving the
service life of civil structures. While successful monitoring provides resolute and staunch …

Output-only modal identification has seen significant activity in recent years, especially in
large-scale structures where controlled input force generation is often difficult to achieve …

Soil-structure interaction (SSI) system is composed of soil and structure that are two
materials with quite different damping behaviors and it is regarded as non-classical damping …

In this paper, the significance of soil–structure interaction (SSI) in optimal placement of
viscous dampers in steel frames is studied. Optimal placement of dampers is determined …

Sparse component analysis (SCA) approach was adopted to handle underdetermined blind
modal identification of structures, where the number of sensors is less than the number of …

We present a new approach to estimate the dynamic stiffnesses of soil-foundation systems
using earthquake-induced response signals recorded on multi-story buildings with sparsely …

Recently the authors developed an output-only (or blind) identification technique for the
modal identification of structures under ambient/free vibrations. In the present study, this …

The 11 March 2011 M 9.0 Tohoku earthquake generated significant long duration shaking
that propagated hundreds of kilometers from the epicenter and affected urban areas …

Response‐only identification of civil structures has attracted much attention during recent
years, as input excitations are rarely measurable for ambient vibrations. Although various …

In the present paper, we extend a previously developed blind modal identification method to
systems with non‐classical damping, which have complex‐valued mode shapes. Unlike …
