It is the carrier's respon'sibility to ensure compliance to the structural <br /> limitations of the existing and/or proposed antenna mounts. l'EP did not perform a site visit to <br /> verify the size, condition or capacity of the antenna mounts and did not analyze antennas <br /> supporting mounts as part of this structural analysis report. <br /> - 7) The following material grades were assumed: <br /> a) Tower legs:ASTM A53-B-46 <br /> b) Tower bracing:ASTM A36 <br /> c) Anchor rods:ASTM A615-75 <br /> This analysis may be affected if any assumptions are not valid or have been made in error. Tower <br /> Engineering Professionals should be notified to determine the effect on the structural integrity of the <br /> tower. <br /> 4) ANALYSIS RESULTS - <br /> Table 5-Section Capacity(Summary) <br /> Section� - i 6omponent � , Cnt�cal - - - ; , j Pass/ ' <br /> EledaUon(tt)_ � � Size � P Iti : �P�,��„ 16_ E /,Ca acd Fa.�l i <br /> No. ; - 1 TYPe � - _ - -_ ; Element; -P - y� <br /> ,-: , - - <br /> � <br /> = = - ° :- _._. . 1 '�.._.._.:; <br /> _. _ . ,. _ : <br /> _ : ` - <br /> Ti 190-1 SO Leg Pipe 2.5 STD 1 -15030.30 53865.90 27.9 Pass <br /> T2 180-160 Leg PIPE 3.5 STD 19 -65368.20 96872.30 67.5 Pass <br /> T3 160-140 Leg Pipe 5 STD 49 -128070.00 157400.00 81.4 Pass <br /> T4 140-120 Leg Pipe 8 STD 75 -198296.00 330771.00 59.9 Pass <br /> — � -- - — <br /> T5 120-113.333 Leg Pipe 8 STD 99 -221326.00 330771.00 66.9 Pass <br /> T6 113.333-106.667 Leg Pipe 8 STD 111 -244626.00 330771.00 74.0 Pass <br /> - _ <br /> T7 106.667-100 Leg Pipe 8 STD 120 -266104.00 330771.00 80.4 Pass <br /> tnxTower Report-version 7.0.5.1 <br />
