| Abstract: | Arc arch pipe is commonly used by span structures. The critical load calculation issues of arc arch pipe under the vertical down load were analyzed. The critical load of entire or half span and the side direction critical load, and the natural frequency of arc arch pipe are calculated, which provides the basis for the design and calculation of arc arch pipe. |
