Wind factors into the design of all construction, including metal buildings. As we enter the peak of the hurricane season running from mid-August to mid-September, let’s examine the meaning of wind zones and their effect on construction.
However, pre-engineered steel buildings are designed to withstand expected wind extremes based on collected historical weather data for the specific location.
Certain areas of the U.S. experience stronger winds than other areas. The FEMA (Federal Emergency Management Agency) map below shows the Wind Zones in the U.S. These wind zones supply engineers and building code officials with the probable top wind speeds a building might face in a given location.
Note that these zones are not based on sustained wind speeds, but on a 3-second gust of wind.
The terrain surrounding a building also affects the wind’s force on the structure. A building right on a coastal beach has little protection from gales sweeping across the water’s surface. However, trees, hills, or other buildings surrounding a structure may act as windbreaks, lessening the force of straight-line winds.
To account for these differences in location, the International Building Code developed these definitions to determine the “exposure” of a structure:
Using the criteria above, steel designers and engineers create metal buildings to meet all current building codes for the specific area.
RHINO Steel Building Systems has never been refused a building permit anywhere— even in the hyper-stringent Dade County, Florida. In fact, our standard loads exceed the building code requirements of many locations. If required by the client, even greater wind loads are possible.
When the winds start to howl, you will be glad you chose a strong, durable RHINO steel building. For details and a free quote on a wind resistant building, call RHINO today on our toll free hotline: 1-888-320-7466.
