Dimensions of Base Plate: The fighters 0.40 x 6.00 m , The vertex 0.20 x 3.80 m Capacity: 8 tons or 350kg/m2 Height above water: 90 mWhy 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.
