Leopold Krügerime. A particular aim is to characterise the underlying linear system using data that is strongly influenced by nonlinearity. A harmonic balance procedure is used to identify a nonlinear discrete spring-mass system, that is modally equivalent to the structure under test. It is found that the inclusi

The vulnerability of our world to earthquakes is rapidly growing due to well-known global trends: proliferation of high-risk construction, such as nuclear power plants, high dams, radioactive waste disposals, lifelines, etc.; deterioration of the ground
