| 摘 要： | 对工程中广泛应用的薄壁箱形截面抛物线拱在均布荷栽和集中荷栽组合作用下的横向稳定性进行了研究，研究表明，集中荷栽移动至拱项处时，较其他位置具有较小的临界值，而其对应的失稳模态差别并不显著。

| Abstract: | This paper researches on the lateral stability of thin-walled box-section parabolic arches subjected to the combinational effect of the uniform load and the concentrated load, which are widely used in the engineering. The results show that the critical value of the concentrated load that moves to the crown of the arch is smaller than that of the other parts of the arch, but their corresponding unstable modal differences are not obvious. |
