Eigenvalue and eigenvector derivatives with respect to system design variables and their
applications have been and continue to be one of the core issues in the design, control and …

Engineering structures seldom behave linearly and, as a result, linearity checks are common
practice in the testing of critical structures exposed to dynamic loading to define the …

This paper represents a continuation of a review on the seismic safety assessment of
historical structures using some selected integrated investigation activities. In the first part of …

This paper proposes a model updating strategy for localised nonlinear structures. It utilises
an initial finite-element (FE) model of the structure and primary harmonic response data …

In order to update analytical models of practical engineering structures, inverse
eigensensitivity method (IEM) has been developed. Though it has nowadays been widely …

Several non-destructive test (NDT) methods, namely visual inspection, hammer sounding,
chain drag, impulse response testing, impact echo testing, ultrasonic (array) echo testing …

Two types of cracks are often encountered in engineering structural systems and these are
the open cracks and the breathing cracks. Existence of open cracks often leads to the loss of …

In engineering practice, both viscous and hysteretic damping models are usually employed
to characterize damped dynamic properties of linear mechanical systems, the identification …

Fractional derivative is increasingly being deployed to improve existing mathematical
models due to its unique capability in describing anomalous behavior and memory effects …

Higher-order frequency response functions (FRFs) are important to the analysis and
identification of structural nonlinearities. Though much research effort has been devoted …
