June 4, 2018 <br /> 288-ft Self-Supporting Tower Structural Modification Analysis Report CCI BU No 816298 <br /> TEP Project Number 26146.157540, Order 412641, Revision 1 Page 3 <br /> 1) INTRODUCTION <br /> This tower is a 288-ft self-supporting tower mapped by IETS Engineering Services in October of 2004. The <br /> original design standard and wind speed are unknown. The tower has been modified multiple times in the past <br /> to accommodate additional loading, however the leg modifications were not considered structurally in this <br /> analysis. TEP visited the site in July of 2008 to perform a post modification inspection. All information provided <br /> to TEP was assumed to be accurate and complete. <br /> 2) ANALYSIS CRITERIA <br /> The analysis has been performed in accordance with the ANSIrfIA-222-G-2-2009 Structural Standard for <br /> Antenna Supporting Structures and Antennas—Addendum 2 using a nominal 3-second gust wind speed of 106 <br /> mph with no ice and 60 mph under service loads with the following design criteria: <br /> Type of Analysis: Rigorous Structural Analysis <br /> Classification of Structure: Class II <br /> Exposure Category: Exposure C <br /> Topographic Category: Category 1 <br /> Earthquake Category: Not Considered <br /> Earthquake effects may be ignored per this standard for site locations where Ss does not exceed 1.0. <br /> (Pasco County Max Ss= 0.10 ). <br /> Table 1 -Proposed Antenna and Cable Information <br /> Center Number Number Feed <br /> Mounting Line of Antenna Antenna Model of Feed Line Note <br /> Level (ft) Elevation Antennas Manufacturer Lines Size(in) <br /> (ft) <br /> 2 � Commscope SBNHH-1 D45C <br /> w/Mount Pipe <br /> i <br /> 197.0 1 Nokia FHFB <br /> 195.0 1 Nokia FRIJ 2 1-1/4 1 <br /> 2 Commscope CBC1921-DF-DC-6X <br /> 3 SitePro 1 MSFAA Mount <br /> 195.0 <br /> j1 3 SitePro 1 F VFA12-HD Mount <br /> Notes: <br /> 1) See"Appendix B-Base Level Drawing"for assumed feed line configuration. <br /> tnxTower Report-version 7.0.5.1 <br />
