桥梁附加荷载结构检算及分析

Check Calculation and Analysis of Bridge Additional Load Structure

研究对正常运营阶段的桥梁施加附加荷载后,其桥梁的承载能力问题,首先对桥梁进行外观检测,调查结构的受损情况并进行评级,然后使用有限元软件Midas Civil进行建模计算.通过有限元模型的计算,分析、比较桥跨结构在附加荷载作用下的受力情况.

This paper studies the bearing capacity of the bridge after the additional load is applied to the bridge in the normal operation stage.Firstly,the appearance of the bridge is inspected,the damage of the structure is investigated and rated,and then the finite element software MIDAS civil is used for modeling and calculation.Through the calculation of the finite element model,the stress of the bridge span structure under the additional load is analyzed and compared.
