Abstract:
Construction of hyperbolic paraboloidal concrete shell roof structures is discussed, including the phases for selection, economy, forms, reinforcing, concrete materials, placing, and curing. Umbrella shells have the greatest potential for economy for large commercial or industrial construction. Gabled shells and saddle shells are suited to long span monumental buildings. Shells require high standards of concrete construction and the close cooperation of the architect, the engineer, and the contractor.
