The arched roof produced by Crimp Curved Roofing Sheet Making Machine also has a bearing effect.
The arches are subjected to different loads, and the line shape of the pressure curve is different. Generally, the pressure curve is determined according to the dead load.
Under the action of the live load, the internal force of the arch may generate a bending moment. The setting will affect the distribution of bending moments inside the arch.
Similar to the rigid frame, the hingeless arch is used only when the foundation is good or there is a stable side span at both arches.
Such arches are rarely used in building construction. There are many applications of double-hinge arches. In order to adapt to the poor settlement of the support on the weak foundation and the deformation of the arched rod, it is better to use the three-hinge arch with a static structure.
