Why a three pinned joint arch ?A three-pinned-arch was chosen for its ability tomove and adjust to the slight movements of the mountain.Whereas a fixed arched would experience massive stressfrom the movement, would crack and possibly fail.Stresses also build up from temperature changes withinthe structure. The three-pinned-arch is unaffected by thesetemperature changes.
