Presentation on Arch Systems

types of arches
Arch is a curved structure designed to carry loads across a gap mainly by compression.
– The mechanical principle of the arch is precisely the same as that of the portal frame. The straight pieces of material joined by sharp bends are smoothed into a continuous curve. This increases the cost of construction but greatly reduces the stresses.
– The geometry of the curve further affects the cost and stresses. The circular arch is easiest to construct, the cattery arch is the most efficient.
– Arches can be three pinned, two pinned or rigid.
