FEM modeling of a concrete arch bridge.

摘要

A Physics doctoral project seeks to reduce the uncertainty of inaccurate visual bridge inspections by producing a remote sensor program to determine and monitor the changes in health of a specified bridge. The Eastern Parkway Bridge was determined as the first bridge to test. As part of this project, a computer-aided analysis of the studied bridge was created using the simulation program ANSYS to assist in documenting the areas requiring the most attention. The model also offered supporting evidence to back the frequencies registered by the optical sensors to ensure proper functioning of the device. Furthermore, the model provided a baseline of the health of the bridge to be used to determine if and where investigation is required after the bridge has suffered a large impact or deterioration.
