Abstract EN
To address the drawback of traditional method of investigating dynamic responses of the continuous girder bridge with uniform cross-section under moving vehicular loads, the orthogonal experimental design method is proposed in this paper.
Firstly, some empirical formulas of natural frequencies are obtained by theoretical derivation and numerical simulation.
The effects of different parameters on dynamic responses of the vehicle-bridge coupled vibration system are discussed using our own program.
Finally, the orthogonal experimental design method is proposed for the dynamic responses analysis.
The results show that the effects of factors on dynamic responses are dependent on both the selected position and the type of the responses.
In addition, the interaction effects between different factors cannot be ignored.
To efficiently reduce experimental runs, the conventional orthogonal design is divided into two phases.
It has been proved that the proposed method of the orthogonal experimental design greatly reduces calculation cost, and it is efficient and rational enough to study multifactor problems.
Furthermore, it provides a good way to obtain more rational empirical formulas of the DLA and other dynamic responses, which may be adopted in the codes of design and evaluation.
