Abstract

"Monolithic dome" is a type of continuous thin shell concrete structure created using an inflated form, reinforcing steel and spray-applied concrete. Designed to withstand pressures exceeding 19 kPa (400lbs/ft 2), or roughly the force of a 490 km/h (300 m/h) wind, the monolithic dome is considered immune from the effects of hurricanes and other natural disasters. Combined with polyurethane foam, monolithic domes use 50% of the energy of comparable U.S. masonry homes. The inorganic, non-combustible and impermeable properties of monolithic dome construction reduce the risk of fire, mold, decay and insect infestation. At roughly $US 1,075/m2 ($US 100/ft2), monolithic domes are 30-40% more expensive than comparable masonry or wood frame residential units. The following research compares the disaster resistance, energy performance, materials use, and cost of monolithic dome structures built in the hurricane prone state of Florida to conventional wood frame and masonry construction.
