The best way to insure that safety of your home is to build with Steel rather than timber.
Steel buildings can be designed for just about any purpose you have in mind. For the best protection, their design must meet state and local building codes. “High wind load” steel buildings can even exceed standards. They are constructed to ensure structural integrity allowing them to resist all types of wind conditions.
For those living in storm and typhoon prone areas, steel buildings can be designed for extremely high wind loads as high as 180 mph. Make sure that all doors and accessories are also certified to meet wind load conditions for maximum performance. But since you generally deal with one supplier when you choose steel buildings; that will not be a problem.
Don't forget earth quakes,
All buildings can carry their own weight plus some added load. Without the addition of earthquake-proof measures, they are generally more resistant to vertical loads or the up and down movements. Side to side movements are another story however. Side to side movements are the weakness of buildings. It is usually the side to side load caused by earthquakes that causes a building to fail and collapse. Side to side loads, or sway loads, are often only resisted by the walls and partitions of a building. Any damages to these can increase the vulnerability of a building to sway loads. This is why measures have to be taken to make buildings resistant to sideways movements.
First and foremost, the weight of the building must be as light as possible. Steel is a reliable material for earthquake resistant design even though it is heavier than concrete. Why? This is because steel is much stronger than concrete, therefore much less steel is utilized to create a building as strong as a concrete one. In simpler terms, a concrete building will weigh less if it were made of steel instead. In this factor alone, Steel buildings are already more earthquake resistant than concrete ones.
Next, steel ground beams are needed to join the feet of the building together. It is better for the installed ground beams to go outside the line of the building to reduce height-to-width ratio of the building resulting to a reduced tendency to overturn. Be sure to hire a local Metal Fabrication company that uses the correct steel.
Before you make your purchase, it is wise to contact you local building code authorities to confirm the code requirements for your area or speak to draftsman
