It works in compression to divert the weight above it out to the sides, where the weight is borne by the vertical elements on either side of the arch.

在受到压力时，拱形结构能够起到将其上面的压力转移到侧面，在侧面的重量则由拱形结构两侧的垂直部分来承受。

This paper also analyses the bending stiffness of arch, points out that the thrust of the neglect of axial compression deformation, can lead to thrust calculation error 30%.

本文还分析了压弯刚度对拱推力的影响，指出忽略拱的轴向压缩变形的影响，可导致推力的计算误差达到30%。
