Apri!9,2015 <br /> 190-ft Self-Support Tower Structural Analysis CCI BU No 826548 <br /> TEP Project Number48i67.31573,Application 289616, Revision 1 Page 3 <br /> 1) INTRODUCTION <br /> This tower is a 190-ft self-support tower designed by Valmont Microflect in January of 1998. The tower was <br /> originally designed for a wind speed of 105 mph per EIA/TIA-222-F for the appurtenances listed in Table 3. The <br /> tower has been modified per reinforcement drawings prepared by Tower Engineering Professionals in July of <br /> 2013. TEP visited the site in November of 2013 to perform a post modification inspection. All information <br /> provided to TEP was assumed to be accurate and complete. <br /> 2)ANALYSIS CRITERIA <br /> The analysis has been performed in accordance with the ANSI/TIA-222-G-2-2009 Structural Standard for <br /> Antenna Supportina Structures and Antennas—Addendum 2 using a 3-second gust wind speed of 106 mph with <br /> no ice and 60 mph under service loads with the following design criteria: <br /> 1) Type of Analysis: 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) Exposure Cateaory: Exposure C <br /> Definition: Open terrain with scattered obstructions having heights generally less than 30-ft. This <br /> category includes flat, open country and grasslands. <br /> 4) Topographic Category: 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 Category: Not Considered <br /> Commentary: Earthquake effects may be ignored per this standard for site locations where Ss does <br /> not exceed 1.0. (Pasco County Max Ss= 0.10). <br /> Table 1 -Proposed Antenna and Cable Information <br /> Center Number Number Feed <br /> Mounting Line Antenna <br /> of Antenna Model of Feed Line Note <br /> Level (ft) Elevation �ntennas Manufacturer Lines Size(in) , <br /> �ft� , � <br /> 3 Andrew I SBNHH-1 D656 <br /> w/ Mount Pipe <br /> 171.0 175�0 3 Ericsson RRUS-11 <br /> 1 3/4 1 <br /> � 3 Ericsson RRUS A2 Module <br /> 171.0 r 3 ` Tower Mounts VFA12-U <br /> Notes: <br /> 1) See"Appendix B—Base Level Drawing"for assumed feed line configuration. <br /> tnxTower Report-version 6.1.4.1 <br />
