Ford ( 7500872 I CCISites <br /> 3.1) Analysis Method <br /> tnxTower(version 8.0.2.1), a commercially 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 /> tnxTower was used to determine the loads on the modified structure. Additional calculations were <br /> performed to determine the stresses in the pole and in the reinforcing elements. These calculations <br /> are presented in Appendix C. <br /> 3.2) Assumptions <br /> 1) The tower and foundation were built in accordance with the manufacturer's specifications. <br /> 2) The tower and foundation 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 Tables 1 and 2, and "Appendix B—Base Level Drawing". <br /> 4) All tower components are in sufficient condition to carry their full design capacity. <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. <br /> 6) All antenna mounts and mounting hardware are structurally sufficient to carry the full design <br /> capacity requirements of appurtenance wind area and weight as provided by the original <br /> manufacturer specifications. It is the carrier's responsibility to ensure compliance to the <br /> structural limitations of the existing and/or proposed antenna mounts. TEP did not analyze <br /> antennas supporting mounts as part of this structural analysis report. <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)1 <br /> Elevation(ft) Component Size Critical Element %Capacity Pass/Fail <br /> 127-122 Pole r TP16.97x16x0.1875 Pole 18.9% Pass <br /> 122-117 I Pole TP17.94x16.97x0.1875 Pole I 35.4% I Pass <br /> 117-112 Pole TP18.909x17.94x0.1875 Pole 54.1% Pass <br /> 112-107 Pole TP19.879x18.909x0.1875 Pole 70.6% Pass <br /> 107-102 Pole TP20.849x19.879x0.1875 Pole 85.1% Pass <br /> 102-100.25 Pole TP21.188x20.849x0.1875 Pole 89.8% I Pass <br /> 100.25-100 Pole+Reinf.
