Abstract

This paper presents the results of modal identification tests that were performed in a twelve span viaduct, located in Auckland, New Zealand, during construction and after completion. These tests are two extensive one-off ambient vibration tests using wireless sensors, conducted to evaluate the structural behavior of the viaduct. The modal identification tests comprised the measurement of accelerations in the structure induced by the usual vehicular traffic crossing over the viaduct. Output-only modal identification methodologies were used to analyze the data obtained in those tests, in order to identify the modal properties of the viaduct in the two different stages.
