Abstract
The ambient vibration is one of the viable output data-only structural dynamic testing options by winds and typhoons. This contribution aims to present the application of a reliable method such as the stochastic subspace identification implemented in a general-purpose software. One of the greatest infrastructures built in Hong Kong, i.e., the Ting Kau Bridge, is addressed as a case study. Results reveal that the proposed method detects both frequencies and mode shapes despite the reduced number of sensors adopted.File in questo prodotto:
