摘要
本文通过对某大跨桥梁的数值模拟,讨论了边界条件对大跨度桥梁模型修正的影响,证实建立大跨度桥梁的初始有限元模型时必须根据实桥情况模拟边界条件,否则难以达到模型修正的目标。
In this paper,by the numerical analysis of a large cross-bridge,to discuss the affect of the boundary conditions to large cross-bridge model updating,the analog boundary conditions confirmed to establish the initial finite element model of the long-span bridges,must be based on the actual bridge,otherwise it is difficult to achieve the target of model updating.
