This paper reviews representative tests used to study the buckling of thin shell concrete structures of two basic types: roof shells and shell walls. Roof shells include spherical domes, cylindrical barrels, hyperbolic paraboloids, and elliptic para-boloids; and shell walls include cylindrical tanks, hyperbolic cooling towers, and torroidal cylinders. The major factors described for each test series are model materials and geometry, boundary conditions, loadings, measuring devices and interpretationsof results. The goal of all such tests is to insure that shell safety is not controlled by buckling.
