r , <br /> July 26,2013 <br /> 190-ft Self Support Tower Structural Modification Analysis CCl BU No 826548 <br /> TEP Project Number 481677359,Application 185469, Revision 4 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. TEP <br /> did not visit the site. All information provided to TEP was assumed to be accurate and complete. <br /> 2) ANALYSIS CRITERIA <br /> The analysis has been performed in accordance with the 2010 Florida Building Code based upon an ultimate 3- <br /> second gust wind speed of 137 mph converted to a nominal 3-second gust wind speed of 108 mph per section <br /> 1609.3.1 as required for use in the TIA-222-G Standard per Exception #5 of Section 1609.1.1 with the following <br /> 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 Category: Exposure C <br /> Definition: Open terrain with scattered obstructions having heights generally less than 30-ft. This <br /> category includes flat, open country, grasslands and shorelines in hurricane prone regions. <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 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 Manufacturer <br /> (ft) Antennas Lines Size(in), <br /> 160.0 160.0 6 CSS CAP-FRO-656 w/Mount Pipe l - - i - <br /> Table 2- Existing Antenna and Cable Information <br /> Center Number Number Feed <br /> Mounting Line Antenna Antenna Model of Feed Line Note <br /> Level(ft) Elevation of Manufacturer Lines Size(in) <br /> 9 Andrew ECC1920-VPUB <br /> 4 Andrew ETW190VS12UB <br /> � I <br /> 9 Cellmax 1 CMA-BDHH/6521/E0-6 <br /> 1940 f Technologies w/Mount Pipe <br /> . <br /> 190.0 2 Nokia FRIE 14 1-5/8 1 <br /> 5 Nokia FRIG <br /> 3 Nokia [ FXFB <br /> 1 Raycap OVP_DC1-48-60-0-15D <br /> 190.0 1 Tower Mounts Platform Mount[LP 715-1]1 <br /> tnxTower Report-version 6.0.4.0 <br />
