Dynamic Testing and Structural Identification of the Hypo Bank Office Complex. I: Experiments

Abstract

Nondestructive dynamic methods are a useful tool in structural engineering. Their purpose is twofold. First, they provide guidance on the validation of a mathematical model of the structure under investigation. Second, repeated tests over time can indicate the emergence of possible damage occurring during the structure’s lifetime. Recent technological progress has generated extremely accurate and reliable experimental methods, enabling a good estimate of dynamic behavior of a structural system. Although experimental techniques are now well-established, the interpretation of measurements still lags somewhat behind. This particularly concerns structural identification due to its nature of inverse problem. In addition, when identification techniques are applied to the study of real-world structures, additional obstacles arise given the complexity of the structural behavior, the inaccuracy of the analytical models used to interpret experiments, measurement errors, and incomplete field data. This study discuss...
