ASCE 7-05 Components & Claddings Wind Pressure for Low Rise Building Walls

Choose Basic Wind Speed  85 90 95 100 105 110 115 120 125 130 135 140 145 150   (MPH)        (90 MPH is a good starting place if well inland. Can range up to 150 MPH in coastal areas.)  
                                                   
Choose Wind Directionality Factor   (Generally, unless dealing with a special situation, it would be best to set this value equal to 1.0)

Choose Occupancy Category   I II III IV  (Generally, Cateogry III will be a conservative choice. Use Category IV for ciritcal structures like hospitals.) 

Choose Exposure Category  A B C D  (Generally, Cateogry C will be conservative. Sometimes Category B may be used if a lot of large upwind obstructions like large buildings or groups of trees.)

Choose Enclosure Classification  OPEN PARTIAL ENCLOSED   (Generally, Partial is a conservative choice if there are breakable glazings in the lower stories.)

Hurricane Prone Region?    (Place a check mark here if in a hurricane-prone region, like South Florida or along the Gulf Coast.)

Choose Maximum Wall Height (ft) (Generally, this would be the worst case value of the eave height above grade.)

Choose Building Length (ft) (Generally, the overall gross value of the building's longest dimension.)

Choose Building Width (ft) (Generally, the overall gross value of the building's shorter dimension.)

Choose Stud Span (ft) (Generally, the worst case unsupported length of the stud between it's end support points. Can be less than Max Wall Height.)

Important Note:  This analysis tool is intended to serve as a general guide to architects and contractors for estimating wind pressure on Components and Claddings (i.e., Curtainwalls) of low rise buildings as per ASCE 7-05.   This tool must NOT be used for construction, final design and/or selection of building components or framing without an independant evaluation by a qualified cold-formed steel design engineer.  There are other factors, other than those listed above, which may impact upon the calculation of these wind pressures, which are NOT addressed by this tool.  K2 Engineering, Inc. and it's employees and associates, specifically disclaim any responsibility and/or liability for failure, or any other sort of consequential damages, resulting from the misuse or mis-application of this tool and its results.   K2 Engineering, Inc. makes no warranties, expressed or implied, regarding this tool.  The User of this tool proceeds at his/her own risk.
