September 10,2017 <br /> 88-ft Monopole Tower Structural Analysis Report CCI BU No 880407 <br /> TEP Project Number 51358.131860,Application 404644, Revision 1 Page 5 <br /> 3.1) Analysis Method <br /> tnxTower (version 7.0.5.1), 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 /> 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) <br /> Section % <br /> I Component Critical Elevation(ft) Size P(K) Pall"(K) Pass/Fail <br /> No. Type Element Capacity <br /> Li 88-42.25 Pole TP20.865x14x0.1875 1 -4.07 877.99 41.7 * Pass <br /> { L2 42.25-0 Pole TP26.83x20.0773x0.1875 2 -7.62 1053.84 69.6 Pass <br /> Summary <br /> Pole(L2) 69.6 Pass <br /> RATING= 69.6 Pass <br /> Table 6-Tower Component Stresses vs. Capacity <br /> Notes Component Elevation (ft) %Capacity Pass/Fail <br /> 1 Anchor Rods - 59.3 Pass <br /> 1 Base Plate - 46.4 Pass <br /> 1 Base Foundation Soil Interaction - 50.4 Pass <br /> 1 ; Base Foundation Structural I 23.9 j Pass <br /> Structure Rating (max from all components)= 69.6% <br /> Notes: <br /> 1) See additional documentation in"Appendix C-Additional Calculations"for calculations supporting the%capacity listed. <br /> tnxTower Report-version 7.0.5.1 <br />
