摘要
基于设计图纸和现场实测,在HYPERMESH中建立了大跨度钢桁架栈桥的全尺度实体模型,通过网格剖分转化为以壳单元为基础的三维精细化计算模型,导入ABAQUS实现了有限元建模.与现场实测数据对比表明,全尺度精细化有限元模型能够较准确地模拟栈桥结构的动力性能,其精度满足工程要求.
Based on the design drawings and on-site measurements,a full-scale solid model of a long-span steel truss trestle was established in HYPERMESH,which was transformed into a 3D refined calculation model based on shell elements through mesh division.Then,the calculation model was imported into ABAQUS to realize finite element modeling.The comparison with the field measured data shows that the full-scale refined finite element model can accurately simulate the dynamic performance of the trestle structure,and its accuracy meets the engineering requirements.
