November 12, 2015 <br /> 285 Ff Se/f Support Tower Structural Analysis CCI BU No 816298 <br /> Project Number 015-00428-00,Application 257452,Revision 13 Page 3 <br /> 1) INTRODUCTION <br /> The existing 285'tower is supported on four legs and has eighteen major sections. It has a square cross section <br /> made of bolted connections,�with "K" brace down, "K1"down, "K2"down, "K2A"down, and portal configurations. <br /> The tower is fabricated with angle legs and angle diagonals. <br /> The tower was mapped by IETS Engineering Services in October of 2004. Original manufacturing drawings are <br /> unavailable; therefore the tower manufacturer, design wind speed, and design standard are unknown. <br /> Modifications designed by IETS Group (Project #: 2005-70954, dated 10/25/05), which consisted of installing <br /> concrete collars and grade beams to the existing foundations, have been considered. <br /> Modifications by B&T Engineering (Project #: 79078, dated 5/6/08), which consisted of replacing select <br /> . redundant horizontals, have been considered. <br /> 2)ANALYSIS CRITERIA <br /> The structural analysis was performed for this tower in accordance with the requirements of TIA-222-G <br /> Structural Standards for Steel Antenna Towers and Antenna Supporting Structures using a 3-second gust wind <br /> speed of 106 mph with no ice and 60 mph under service loads, exposure category C. � <br /> Table 1 -Proposed Antenna and Cable Information <br /> � i 6enter i Number{ ' ' Number; Feed ? <br /> Mounting Line, { - I Antenna � <br /> , of Antenna Model of Feed; Line Note; <br /> Level (ft); Elevation= Manufactu�er <br /> �ft� i Antennas Lines• � Size(in) <br /> �I 3 CSS ' X7GFR0-860-VRO w/ <br /> Mount Pipe <br /> l X7CQAP-86-865-VRO w/ <br /> I 177.0 I 177.0 3 CSS Mount Pipe 1 I 1-1/4 I 1 <br /> I � 3 Ericsson RRUS12/RRUS A2 I I I <br /> I � 3 Raycap RCMD'C-3315-PF-48 I I <br /> ��___—_��v___ 3 CI Wireless VF13-30-96 �_—______�_�_____�___� <br /> Notes: <br /> 1) See Appendix B for the proposed coax layout <br /> Table 2-Existing and Reserved Antenna and Cable Information <br /> : Center � Number� � ! .
