The 3rd International Conference on Structural Health Monitoring of Intelligent Infrastructure Vancouver, British Columbia, Canada November 13-16, 2007 INTEGRATED ANALYSIS OF INHOMOGENEOUS STRUCTURAL MONITORING DATA OF A MONOLITHIC BRIDGE Werner Lienhart Graz University of Technology, Austria Fritz K. Brunner Graz University of Technology, Austria Abstract In structural monitoring geodetic sensors (tacheometers, GPS, …) are commonly used in combination with other sensors, like level sensors or fiber optic sensors. The hybrid measurements are inhomogeneously distributed throughout the structure as well as in time. For a detailed understanding of the structural behavior the data from all sensors need to be analyzed. For this purpose, an Integrated Analysis Method (IAM) has been developed using a Finite Element Model (FEM) to combine all measurement data for the deformation analysis. The proposed IAM is applied to the deformation analysis of a monolithic bridge, which was monitored with embedded fiber optic sensors, inclinometer data and geodetic measurements for more than two years. MONOLITHIC BRIDGE To date the widening of alpine roads is mostly done using excavations with retaining walls. However, the construction of retaining walls is expensive and requires substantial earthworks, which adversely affect the sensitive alpine ecological system. In order to overcome these problems, a new bridge construction was developed by the engineering office Eisner (Graz, Austria).
