30、 conditions, this paragraph will be modified to provide for a corrosion allowance.Determine basic wind speed for use with ANSI procedure from ANSI,UFC 3 310-01 LOAD ASSUMPTIONS FOR BUILDINGS or UFC 3-320-05A STRUCTURAL DESIGN CRITERIA FOR STRUCTURES OTHER THAN BUILDINGS. The choice between the ANSI
31、and AWWA procedures allows SECTION 33 16 15 Page 6Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-the supplier to provide a tank using the AWWA approach up to the point at which the ANSI procedure will provide the greater pressure. (This usually occu
32、rs with a basic wind speed around 145 km per hour (90 miles per hour), depending on the height of the tank.)Use 1200 Pa (25 psf) snow load for most heavy snow climates; delete snow load where maximum snow is insignificant. In some cases, local climate and topography will dictate that a value greater
33、 than 1200 Pa (25 psf) be used for snow loading. This may be determined from UFC 3 310-01.Provide seismic requirements for tank related equipment supports, if a Government designer is the Engineer of Record, and show on the drawings.

NAVFAC P-355, “Seismic Design for Buildings,“ does not allow the use of pedestal type elevated tanks in areas of moderate and high seismic activity, so use only elevated tanks with cros

No additional thickness for corrosion allowance will be required. Design metal temp

The elevated tank shall be designed for a basic wind speed of _ km/hourmph in accordance with ASCE 7 or designed in accordance with AWWA D100 wind load design, whichever provides the greater pressure. The elevated tank shall be designed for a snow load of 1200
