Abstract

The Echindome is a flat bottomed shell of revolution based on the shape of the common Sea Urchin. It has application in underwater storage or habitation for both industrial or leisure purposes.

The structure could operate either founded on the sea bed or tethered to it in a floating submerged attitude. One of the most complex loading forms which such structures would have to sustain is that due to concentrated effects.

The paper considers experimentally the behaviour of a small scale prototype under the action of a general regime of point loads. Computer methods of simulation are presented for the structure under these conditions and comparisons are made between predicted and experimental measurements of deformation and stresses. Implications for design are discussed.
