The Effect of the Secondary Dead Load on Vibration Characteristics of a Steel Box Girder Footbridge Model

Abstract:

Making field test and finite element simulation on East Third Ring Road Xiaobawang footbridge in Beijing, considering the effect of the deck loads of the bridge on the model calculation results, we can find the effect of the secondary dead load on vibration characteristics of the footbridge model. Comparison of the frequencies of model before and after applying the secondary dead load make us know that applying dead load will lead to the lower frequency of bridge. In the process of the bridge finite element analysis, factors to consider should be more comprehensive and the way to simulation should be more realistic so that the results of finite element simulation can be closer to the actual.
