The principal aim of this book is to describe the new developments in the area of structural testing, particularly those based upon the principle of fusing numerical and experimental methods such as real-time dynamic substructuring and hardware-in-the-loop testing. These methods have significant potential for component testing which will enable engineering designers to significantly reduce design uncertainty and lead times. In addition to the hybrid methods, chapters on the latest developments in more established techniques, such as shaking table testing, give a completely up-to-date survey of structural testing methods. The chapter contents reflect the multidisciplinary nature of the work by integrating cutting-edge research from the fields of non-linear dynamics, automatic control, numerical analysis, system modelling and mechatronics. The result is a detailed treatment of state-of-the-art techniques and tools required for experimental testing of structures.
