摘要:
探讨了以结构安全评估为目标的大跨斜拉桥基准有限元模型建立与修正的策略与方法.采用基于灵敏度分析的模型参数修正方法建立并修正了润扬大桥斜拉桥的整体动力分析模型.在此基础上建立了扁平钢箱梁的局部应力分析模型,并采用子模型方法进行钢箱梁整体尺度与局部尺度之间的跨尺度衔接.分析结果表明,润扬大桥斜拉桥多尺度有限元模型的计算结果与实桥测试结果吻合良好,说明该多尺度模型能够较好地满足桥梁结构损伤诊断与状态评估的技术要求,可以作为该桥结构安全评估的基准有限元模型.
Abstract:
The strategy and method of baseline finite element modeling of long-span cable-stayed bridges for the purpose of structural safety evaluation is discussed. With respect to the Runyang Cable-Stayed Bridge, the integrated dynamic analysis model is established and updated using the sensitivity-based model updating method. The local stress analysis model for steel box girder is then constructed and the submodeling method is employed for the multi-scale connection of these two models. The analysis shows that the calculation results by multi-scale finite element model of Runyang Cable-Stayed Bridge fit in well with the field test results. Therefore the multi-scale models are necessary for structural damage diagnosis and condition assessment and can serve as a baseline model for structural safety evaluation.
