It is a misconception to believe that hurricane anchor is placed in the foundation. On the contrary, hurricane anchors shall be installed in the roof truss chords and connected to a column or stiff wall.

Any wind force creates an uplift force in a building. These uplift forces are normally harmless and do not need to be taken into account since the weight of the structure will sufficiently counteract with the uplift force an nivellate it. However, it is a different story with a hurricane force wind. These exrtremely high wind forces create tremendously high uplift forces and will blow the roof away when the roof truss system is not properly anchored. The uplift reaction forces are transferred to the foundation via the hurricane anchors, whereas the foundation anchors also need to be designed to safely absorb these forces (it is normal engineering practice to oversize the foundation to utilize its weight to a factor of 1.2 x the total uplift force). 

BALI PREFAB WORLD applies vertical steel rods, tighlty installed onto the truss chords as to deal wth the calculated uplift forces.

So far all of our units built in a cyclone area have safely sustained a hurricane force wind:

In September 2004 one of our buildings withstood hurricane Ivan that struck the Cayman islands
In November 2009 a 2-storey unit designed and prefabricated by us lost only some roof tiles when the island of Sta. Lucia in the Caribbean was hit by hurricane Thomas
Eary November 2013 the Phillipines were hard hit by typhoon Haiyan. Our A-2 model sustained the 315 km/h (196 Mph) storm

 

 

 

 

 


 

 

Reviews from Bali Prefab World

"Bali Prefab World is doing an excellent job of modeling the 3-D finite element frame structure in STAAD and now analyzing the individual members to ensure that they are not overstressed. I have just completed a review of the column analysis for the primary columns supporting the roof, and it is well presented and clearly shows the members are adequate size. I have not seen anything like this before the way this report was presented and prepared with the vast knowledge behind. This type of analysis would not have been possible by hand calculation because of the complexity of the structure. Job well done Bali Prefab World".
