Ju/y 30,2012 <br /> 190 Ft Se/f-Supporting Tower Structura/Ana/ysis A2G0082A Pasco County(VS) <br /> Project Number 110908, Revision 5 Page 3 <br /> 1) INTRODUCTION <br /> This tower is a 190-ft self-supporting tower designed by Valmont in November of 1998 The tower was originally <br /> designed for a fastest mile wind speed of 105 mph with no ice and 50 mph under service loads per TIA/EIA-222- <br /> F for the appurtenances listed in Table 2. TEP did not visit the site. All information provided to TEP was <br /> assumed accurate and complete. <br /> 2)ANALYSIS CRITERIA <br /> The structural analysis was performed for this tower in accordance with the ANSI/TIA-222-G-2-2009 Structural <br /> Standard for Antenna Suoportinq Structures and Antennas-Addendum 2 and the 2010 Florida Buildina Code <br /> based upon an ultimate 3-second gust wind speed of 137 mph converted to a nominal 3-second wind speed of <br /> 106.1 mph per section 1609 3.1 as required for use in the TIA-222-G Standard per Exception#5 of <br /> Section1609.1 1. Exposure Category B and Risk Category II were used in this analysis along with the following <br /> criteria. <br /> 1) Tvpe of Analvsis: Rigorous Structural Analysis <br /> 2) Classification of Structure: Class II <br /> Definition: Structures used for services that due to height, use or location represent a significant <br /> hazard to human life and/or damage to property in the event of failure and/or used for services that <br /> may be provided by other means. <br /> 3) Exqosure Cateaorv: Exposure B <br /> Definition. Urban and suburban areas, wooded areas, or other terrain with numerous closely <br /> spaced obstructions having the size of single-family dwellings or larger <br /> 4) Topopraqhic Cateaorv: Category 1 <br /> Definition: No abrupt changes in general topography, e.g.flat or rolling terrain, no wind speed-up <br /> consideration shall be required. <br /> 5) EarthQUake Cateporv: Not Considered <br /> Commentary� Earthquake effects may be ignored per this Standard for site locations where Ss <br /> does not exceed 1.0.
