Abstract
[Abstract]: Dynamic behavior of a hybrid composite bridge girder was investigated using experimental and analytical methods in order to understand dynamic performances of girders under operational loading conditions. The vibration response of the girder was measured using a single-point impact excitation. A dynamic analysis of the girder was performed using Euler – Bernoulli beam theory and Timoshenko beam theory for comparison. Also the girder’s hybrid composite configuration was modeled and a detailed dynamic analysis was performed using finite element (FE) techniques on FE software STRAND7. It has been found that both FEA and analytical frequencies are at par with the experimental results. This paper outlines some conclusions on dynamic characteristics of hybrid bridge girders and the rationale of using engineering beam theories and FEA in hybrid beam analysis.
