Ju/y 30,2012 <br /> 190 Ft Se/f-Supporting Tower Structura/Ana/ysis A2G0o82A Pasco County(VS) <br /> Project Number 110908, Revision 5 Page 5 <br /> 3.1) Analysis Method <br /> tnxTower (version 6.0.4.0), a commerciaily available analysis software package, was used to create a <br /> three-dimensional model of the tower and calculate member stresses for various loading cases <br /> Selected output from the analysis is included in Appendix A. <br /> 3.2) Assumptions <br /> 1) Tower and structures were built in accordance with the manufacturer's specifications <br /> 2) The tower and structures have been maintained in accordance with the manufacturer's <br /> specification. <br /> 3) The configuration of antennas, transmission cables, mounts and other appurtenances are as <br /> specified in Table 1 <br /> 4) TEP assumed the following material properties� <br /> a) Legs: ASTM A572 Gr. 50 <br /> b) Bracing:ASTM A36 <br /> c) Anchor Bolts. ASTM A354-BC <br /> 5) Serviceability with respect to antenna twist, tilt, roll, or lateral translation, is not checked and is <br /> left to the carrier or tower owner to ensure conformance. See Table 6. <br /> 6) Tower Engineering Professionals, Inc. (TEP) did not analyze antenna supporting mounts as part <br /> of this structural analysis report. TEP assumes that all antenna mounts and mounting hardware <br /> are structurally sufficient to carry the full design capacity requirements of appurtenance wind <br /> area and weight as provided by the original manufacturer specifications. It is the carrier's <br /> responsibility to ensure compliance to the structural limitations of the existing and/or proposed <br /> antenna mounts. TEP did not perform a site visit to verify the size, condition or capacity of the <br /> antenna mounts <br /> 7) This report is not a construction document. <br /> 4) ANALYSIS RESULTS <br /> Table 4-Section Capacity(Summary) <br /> �Ion Elevatlon(ft) CO T�°t Size E��t p(�b� F"P allow % Pass 1 Fall <br /> (Ib) Capadty <br /> T1 190-180 ' Leg i PIPE 2.5 STD(SCH 40) � 3 -10644.600 �57361.699 � 18.6 � Pass <br /> T2 180- 160 Leg PIPE 3_5 STD ' 21 -48512.602 !104062.000� 46.6 � Pass <br /> T3 160-140 Leg Pipe 5 STD(SCH40) 51 -95587 703 �169395.000' 56.4 Pass <br /> T4 140-120 Leg Pipe 5 STD(SCH40) 75 -152292.000�169395.000� 89.9 Pass <br /> - - - - --, - - , <br /> T5 120- 100 Leg PIPE 8 STD(SCH40) 99 -210590.000 �358212.000! 58.8 Pass ; <br /> T6 100-80 Leg Pipe 10 STD(SCH40) � 123 -264286.000�498329.000� 53.0 Pass <br /> T7 80-60 Leg Pipe 10 STD(SCH40) 141 -323140.000 i498329.000� 64.8 Pass <br /> T8 60-40 Leg Pipe 12 STD(SCH40) 159 -382016.000�623679.000� 61.3 Pass <br /> T9 40-20 Leg Pipe 12 STD(SCH40) 177 -440095.000 f623679.000 j 70.6 � Pass <br /> T10 20-0 Leg P12EH ' 195 -497646.000 �822322.000� 60.5 r Pass ' <br /> Ti 190-180 .
