A Recap of Hurricanes, Tornadoes, Earthquakes
a Lighting Strike and American Ingenuity Domes
Our best wishes go out to all the people affected by Hurricane Sandy and the Oklahoma tornado. American Ingenuity has had its domes go through Hurricane Andrew (165 mph winds with burst of 212 mph winds...category 5) and a tornado spawned by Andrew and Hurricane Katrina (140 mph winds...category 4) with no structural damage. Hurricane Sandy had 90 mph winds and water surges. Ai did not have any of its domes in Sandy's path. If building near coastal areas, build your Ai dome on pilings and concrete platform to allow water surge to go under the dome.
Q: What wind and snow loads will the Ai dome withstand?
For over thirty years, American Ingenuity's dome design has proved itself by withstanding the following acts of nature with no structural damage: Hurricane Andrew's 165-212 mph winds, a tornado that rolled up a steel horse trailer and slammed it against the Menendez dome, four hurricanes in 2004, Hurricane Katrina, 6.6 earthquake in 2006, sub-zero temperatures and heavy snow loads of the Northwest Territory of Canada, a 30" in diameter 115 foot tall hickory tree impact, a lighting strike and many other conditions.
More about steel horse trailer impact: American Ingenuity warranties their concrete domes against 225 mph hurricanes and #4 tornadoes. Since our dome kit manufacturing business started, Ai has sold kits into 47 states and thirteen foreign areas. Since then Ai does not know of any of our client's domes suffering any damage due to hurricanes, earthquakes or tornadoes except for one dome during Hurricane Andrew. During Andrew a tornado slammed a two wide metal horse trailer against a 45’ Ai Dome. A riser wall of the dome ended up with a hairline crack and a missing chunk of concrete. The dome owner caulked the crack, mixed up some fiber concrete to fill the chunk and then painted over the area.
More about the tree impact: There was no damage to the Brack's 48' Ai dome or its basement after winds in excess of 75 mph hit North Carolina in July of 1996. The real test came when a 115' high, 30" in diameter hickory tree was blown over and fell on their dome. The impact broke a 10" diameter branch. The tree slid off the dome and landed on a deck post driving it and it's 16" square concrete footer 6" further into the ground. The insurance agent who inspected the damage to the deck conveyed his amazement about the dome's strength with this comment, "If that had been a frame house the tree would have ended up in the basement!"
More about the lightning strike: American Ingenuity's 45' office dome withstood another one of nature's most powerful forces, a LIGHTNING STRIKE. The lightning hit the outer edge of an entryway and the only damage it did to the dome was to knock off a handful of concrete at the point of impact! A couple of our computers have not been the same since, but the cost to repair the dome did not exceed $30 in materials and labor.
More about heavy snow loads: In 1995 Mr. and Mrs. Carroll visited Robens and Tom Napolitan's dome. Robens was enthusiastic, but Tom was not. Tom explained to the Carroll's, "its all HER idea, I didn't want a dome." Mary Carroll phoned the Napolitans in 1996. Mrs. Carroll said you couldn't keep Tom quiet this time. He had nothing but wonderful things to say about the dome and had completely turned around about the wonders of living in an American Ingenuity dome.....ROOFS HAD COLLAPSED in their area under several feet of snow, but NOT HIS DOME! Tom's turnaround sold Mary and her husband on an Ai dome.
This recap starts with the most current hurricane, Ike.
HURRICANE IKE, September 2008
third most destructive hurricane
to ever make landfall in the United States
Mr. & Mrs. Evans of Seabrook, Texas went through Hurricane Ike in an American Ingenuity dome home (48’ and 34’ dome). Vicki states, “Our domes had no damage although we had significant tree damage on our one acre lot. We slept through Hurricane Ike and only the next day realized how violent the hurricane had been. Whole communities two miles away in the Galveston Bay area were destroyed. Our neighbors could not believe that we slept through the storm….they told us that they had been up all night due to the violent winds and noise. We did not have to replace or repair our roof. YEA! Many of our neighbors have spent the last several months replacing their roofs. Because of the aerodynamic shape of the dome, its steel reinforced concrete construction and its thick insulation, the hurricane sounds were not absorbed through the walls of the dome and our domes had no damage. We are really glad that we built our domes back in 1991.”
The following info about Ike came from the Wikipedia dictionary.
Hurricane Ike was the third most destructive hurricane to ever make landfall in the United States. It was the ninth named storm, fifth hurricane and third major hurricane of the 2008 Atlantic hurricane season. It was a Cape Verde-type hurricane, as it started as a tropical disturbance off the coast of Africa near the end of August, then tracked south of Cape Verde and slowly developed. On September 1, 2008, it became a tropical storm west of the Cape Verde islands.
By the early morning hours of September 5, Ike was a Category 4 hurricane, with maximum sustained winds of 145 mph (230 km/h) and a pressure of 935 mbar (27.61 in Hg). That made it the most intense storm in the 2008 Atlantic hurricane season. Ike also had the highest IKE (Integrated Kinetic Energy) of any Atlantic storm in history. Integrated Kinetic Energy is a measure of storm surge destructive potential, similar to the Saffir-Simpson Hurricane Scale, though the IKE is more complex and in many ways more accurate. On a scale that ranges from 1 to 6, with 6 being highest destructive potential, Ike earned a 5.6 on September 11 at 12:30 p.m. EDT. In comparison to Ike, hurricanes Katrina and Wilma, both from the 2005 Atlantic hurricane season peaked at 5.1. As such, had Ike made landfall as a Category 3 or higher, the hurricane would have likely had a record breaking storm surge and the potential for damage could have been worse than what was seen with Hurricane Katrina. However, Ike made its final landfall in Baytown, Texas, United States as a Category 2 hurricane.
Ike was blamed for at least 195 deaths. Of these, 74 were in Haiti, which was already trying to recover from the impact of three storms earlier that year: Fay, Gustav, and Hanna. In the United States, 112 people were killed, and 34 are still missing. Damages from Ike in US coastal and inland areas are estimated at $24 billion (2008 USD), with additional damage of up to $4 billion in Cuba, $200 million in the Bahamas, and $60 million in the Turks and Caicos, amounting to a total of $28.26 billion in damages. Ike was the third costliest U.S. hurricane of all time, behind Hurricane Andrew of 1992 and Hurricane Katrina of 2005.
Hurricane Katrina...category 4 wind speed 140 mph
Hurricane Katrina caused many deaths and over $34 Billion dollars in damages making it one of the worst American Catastrophe. Ai had domes in its direct path. The domes suffered no structural damage.

According to information from the Insurance Information Institute, the 2004 Florida Hurricanes (Charley, Frances, Jeanne and Ivan) are among the 10 costliest U.S. catastrophes when measured by insured damages. At the time of the 2004 hurricanes over 123 Ai domes were built in Florida, not one of them suffered any damage due to these hurricanes. Ai had domes in the direct path of Charley in the cities of Port Charlotte and Fort Meyers. News reports stated that in 2004 one out of every five residences in Florida suffered damage due to the hurricanes. The following was taken from the Insurance Information Institute's web site www.iii.org On their front page click on "Facts and Statistics," then click on Catastrophes. As of 2009, Florida allows a wind mitigation form to be filled out by a certified engineer. Ai domes that have had this form submitted to their insurance companies have paid greatly reduced prices for the hurricane part of their insurance. One client's premium went from $850 to $90.
