Abstract:
The finite element(FE)modeling for the purpose of damage alarming, damage identification and safety evaluation are discussed with respect to the FE modeling and model updating of Runyang Cable-stayed Bridge. According to the characteristics of the steel deck and requirements of safety evaluation, the three-dimensional elaborate FE model is established and modified. The comparisons between the field measurement results and the dynamic properties of the FE model prove the FE model to be correct and reliable. The FE simulation method of the orthotropic steel deck is discussed, on the basis of which the simplified FE model is established for the purpose of structural damage alarming and identification. The comparisons of dynamic properties between the elaborate model and simplified model validate the effectiveness of the FE simplified simulations of the orthotropic steel deck.
