Roofs Built To Resist Earthquakes

When designing earthquake safe structures the first consideration is to make the highest bit the roof as light as possible.

Roofs built to resist earthquakes.

One way to resist ground forces is to lift the building s foundation above the earth. Earthquake resistant or aseismic structures are designed to protect buildings to some or greater extent from earthquakes. This can be done with profiled steel cladding together with a layer of added insulation. This is best done with profiled steel cladding on light gauge steel zed purlins.

While no structure can be entirely immune to damage from earthquakes the goal of earthquake resistant construction is to erect structures that fare better during seismic activity than their conventional counterparts. In south florida all roofs must be built to withstand 146 mph wind forces and by using metal ties strapping and other reinforcement most builders use wood to meet this standard. A 30 degree roof slope has the best results. Kelvin doerr director of engineering and technical services at fox blocks says basically it comes down to stronger thicker structural members with better connections.

This is difficult because some sort of framing is vital. Here are some of the methods used to help buildings withstand earthquakes. Create a flexible foundation. Since earthquakes release energy that pushes on a building from one direction the strategy is to have the building push the opposite way.

Once these walls shake a bit the entire strength is lost and the building will collapse or pancake during an earthquake. It can have a roof slope between 3 and 15 degrees. Gable roofs are generally more common because they are cheaper to build. The roof of an earthquake resistant building must be as light as possible too.

This can also have double skin with spacers and insulation.
