摘要:
通过对润扬长江公路大桥斜拉桥的有限元建模和模型修正过程,探讨了大跨桥梁结构以损伤预警、损伤识别与安全评估为目标的有限元建模策略.根据斜拉桥桥面系的特点和安全评估的要求,建立并修正了三维精细有限元模型,动力特性分析结果与实测结果的对比证实该有限元模型的正确性和可靠性.探讨了正交异性桥面系的有限元模拟方法,并以损伤预警与损伤识别为目标建立了简化有限元模型.与精细模型的动力特性对比表明,该模型可作为结构损伤预警与损伤识别分析的有限元模型.
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.
