Modal Analysis of a Thin-Walled Box-Girder Bridge and Railway Track Using Finite Element Framework

Modal analysis has received widespread acceptance in past few decades for a wide range of applications. Bridges and buildings are two of the most popular structures that use this application in the context of civil engineering. The current study aims to apply finite element technique to estimate the...

Bridges and buildings are two of the most popular structures that use this application in the context of civil engineering.

The curved bridge is numerically modeled using thin-walled box-beam finite elements that take into account torsional warping, distortion, and distortional warping, all of which are important characteristics of thin-walled box-girders.
