基于响应面法的钢-砼混合梁悬索桥有限元模型修正

Updating the finite element model of steel-concrete composite beam suspension bridge based on response surface method

有限元初始模型往往与实际结构间存在着某些误差,不能准确反映桥梁实际的工作状态。作者建立了某钢-砼混合梁悬索桥的有限元模型,基于桥梁荷载试验所得响应,建立其响应面模型进行优化计算,修正了有限元模型。

There are some errors between the established finite element initial model and the actual structure, which cannot accurately reflect the actual working status of the bridge. The author established a finite element model of a steel-concrete composite beam suspension bridge, based on the response obtained from the bridge load test, established its response surface model for optimization calculation, and modified the finite element model.
