| 摘 要： | 在大跨径拱桥的设计中,悬链线被较多地作为拱轴线,计算拱轴系数是拱桥设计的重要组成部分,但目前确定拱轴系数的常规方法有不足之处.基于APDL参数化语言,建立了实桥模型,运用ANSYS软件强大的有限元计算能力和APDL参数化语言的灵活性,实现了拱轴系数m的优化设计.此方法用于拱桥设计中拱轴系数的确定,可弥补常规方法的不足,对提高拱桥设计的计算效率和精度有一定的参考价值.

| Abstract: | Catenary is usually used as arch axis during a design of large span length arched bridges. Calculation of the arch-axis coefficient is important for arch bridge design. However, the current calculation method for calculating arch-axis coefficient has some disadvantagts. In this paper, a model of arch bridge is established using finite element software ANSYS and APDL parametric language, optimization design of areh-axis coefficient can be realized conveniently. Therefore, the method based on the APDL parametric language can improve calculation efficiency and precision, and can be a reference for a design of arched bridges. |
