摘要
基于能量原理推导了有横撑系杆拱桥侧向弹性稳定承载力的解析计算公式,并通过算例的有限元数值解验证了提出的解析公式的正确性,最后讨论了结构参数对稳定承载力的影响。推导的稳定承载力解析式对系杆拱桥的分析与设计具有实用意义。
With the principle of the minimum potential energy, an analytical solution for the lateral critical buckling load of tied-arch bridges was studied. To verify the solution's accuracy, a practical bridge was analyzed using the formula presented this paper. The structural parameter influence on the lateral buckling load was also investigated.
