Types and Forms of Shell Structures

DOME AND BARREL VAULT

In the structure shown above the side of the square dome suggests the shape of a barrel vault. These are really independent structures since the structural elements are all formed before the attachment has been made and could be cut apart without destroying the structure.

Because of the form of the plan, this structure suggests a church or other auditorium with a large central area and adjacent seating.

Vaults can be attached to any of the four sides to produce a T shape or a cross shaped building and the wings may be of various lengths to suit the seating arrangement. The ties across the sides of the dome can be eliminated by L shaped walls acting as thrust abutments.
