摘要
分别采用MIDAS梁单元模型、MIDAS梁板结合单元模型及ANSYS板单元模型,建立了钱塘江公铁两用钢桁梁桥模型,分析其动力特性。结果表明,采用空间板壳法能更加精确地模拟钢桁梁的结构动力特性。研究结果可为今后钢桁梁桥的模型建立提供参考,并为进一步的静力和动力分析奠定基础。
MIDAS beam element model,MIDAS beam plate combined element model and ANSYS plate element model are used to establish the model of Qiantangjiang steel truss bridge for highway and railway and analyze its dynamic characteristics.The results show that the spatial plate shell method can more accurately simulate the structural dynamic characteristics of steel truss beams.The research results can provide reference for the model establishment of steel truss bridge in the future,and lay a foundation for further static and dynamic analysis.
