Barrel vault shape is quite similar to arch shape, but barrel vaults are more curved in shape. They can be semi circular or circular in shape. Also the radius of each curve can vary creating a unique shape and style.
Vault shape tensile Structures generally range from 3 m span upto 30 m span. But there is no limitation; it can go beyond this range depending on heaviness and design of the steel structure.
Barrel vault Shape Tensile structures are made of a series of parallel arches along the length of the structure which are futher tied by steel tubular perlin members. Fabric is designed using the concept of anticlastic curvature, conve along the arch and concave across the arches.
