摘　　要：为了解决桁架跨越结构在使用过程中出现的强度问题,本文在理论计算的基础上,采用有限元软件Ansys对桁架跨越结构做了各种常见载荷下的强度分析。本文充分考虑了桁架桥自重、地震、洪水等复杂情况,采用理论计算和有限元分析相结合的方法保持了足够的精确度,从而为桁架跨越结构的设计及使用阶段的维护提供了必要的理论基础。Based on theoretical calculation,the finite element software Ansys is used to analyze the strength of truss span structures under various common loads. In this paper, the complex situations such as dead weight, earthquake and flood of truss bridge are fully considered. The combination of theoretical calculation and finite element analysis has maintained sufficient accuracy, which provides a necessary theoretical basis for the design and maintenance of the truss span structure in the service phase.
