Hurricane Rita hit Louisiana and demolished nearly everything that came on its way. There was one particularly resilient and lucky house that weathered the hurricane. While owners returned to the log home, their hopes sank, nothing but destroyed houses one after other. However, their log home stood tall and everything was on its place. Miracle? Heritage Log Homes thinks that their patented thru-bolt anchoring system is to thank for.
Personally I would also add the structural flexibility of every log home to the explaining reasons. Bolted or not, logs are not permanently fixed with mortar and plaster. There is always possibility for some bending before breaking occurs. In hurricane, log homes are like Japanese katanas – they have hard edge that cuts the wind and flexible part that protects edge from breaking.
