Three-hinged arch



An arch with hinges at the abutments and one in the middle.

This type of arch allows movement of the parts to accommodate changes due to temperature and settlement. You may have to look widely to see one, but they are easily recognised. They may be called "3-pinned" arches, but you may not be able to see the three "pins".
