Vibration signals are naturally available and can be readily measured from many types of engineering systems through a variety of low cost data acquisition systems and sensors under normal operating conditions. Based on the appropriate processing of the collected signals, rich information for the structural dynamics can be extracted and used for linear and nonlinear modeling, structural health monitoring, active vibration control, modal analysis, and further system insight that may lead to the design of improved and sustainable systems as well as to increase of safety and comfort.

The aim of this special issue is to collect studies with the state of the art in the abovementioned scientific areas with applications in engineering and preference in actual systems and experimental procedures. Research articles as well as review articles are welcome also novel methodologies, algorithms, and groundbreaking applications. Authors are invited to contribute high quality original articles.

Potential topics include, but are not limited to:

• Linear and nonlinear system identification
• Nonlinear techniques for damage diagnosis
• Advanced signal processing and statistical methods in structural health monitoring
• Test planning/optimization
• Dynamical model validation/updating
• Optimal sensor placement techniques for structural health monitoring
