| 摘 要： | 本文研究两端简支的正弦浅拱当一端支座突然沉陷并受冲击载荷作用时的屈曲行为,文中考虑了拱的一阶变形模态,并给出了静态屈曲和冲击屈曲临界载荷的计算,分析表明支座沉陷量对静力屈曲的影响大于对冲击屈曲的影响。

| Abstract: | The impact buckling of a shallow arch is studied, which is subjected to a sudden support settlement and a sudden lateral pressure. By considering the first deformation mode, both the static buckling load and the impact bucking load are given. It is shown that the support settlement is more sensitive to static buckling than to impact buckling |
