Revision 1 Page 4 I(b <br /> 3.1) Analysis Method <br /> RISA-3D (Version 17.0.4), a commercially available analysis software package, was used to create a <br /> three-dimensional model of the antenna mounting system and calculate member stresses for various <br /> loading cases. <br /> A tool internally developed by TEP, using Microsoft Excel,was used to calculate wind and seismic loading <br /> on all appurtenances, dishes, and mount members for various load cases. Selected output from the <br /> analysis is included in Appendix B "Software Input Calculations". <br /> This analysis was performed in accordance with Crown Castle's ENG-SOW-10208 Tower Mount Analysis <br /> (Revision D). <br /> 3.2) Assumptions <br /> 1) The antenna mounting system was properly fabricated, installed, and maintained in good <br /> condition in accordance with its original design and manufacturer's specifications. <br /> 2) The configuration of antennas, mounts and other appurtenances are as specified in Table 1 and <br /> the referenced drawings. <br /> 3) All member connections are assumed to have been designed to meet or exceed the load carrying <br /> capacity of the connected member unless otherwise specified in this report. <br /> 4) TEP did not analyze the collar mount connection to the pole and assumes it to have sufficient <br /> structural capacity to transfer the applied forces from the mount to the tower. <br /> 5) The following structural member sizes were assumed based on photographs: <br /> a) Kicker: L21hx21/2x3/16"ASTM A36 <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 /> antenna mounting system. <br /> 4)ANALYSIS RESULTS <br /> Table 3 -Mount Component Stresses vs. Capacity (Platform w/ Support Rail Mount)3 <br /> Notes Component Critical Mount % Capacity Pass/Fail <br /> Member Centerline (ft) <br /> 1 Face Horizontals FF-HB 127.0 18.4 Pass <br /> 1 Support Rails HR-3 127.0 95.7 Pass <br /> 1 Support Horizontals SA-2 127.0 17.5 Pass <br /> 1 Support Bracings GSI-2 127.0 12.0 Pass <br /> 1 Kickers K-1 127.0 21.8 Pass <br /> 1 Mount Pipes MP-4 127.0 69.4 Pass <br /> 2 Connection Bolts - 127.0 8.2 Pass <br /> 2 Connection Plate - 127.0 8.8 Pass <br /> Structure Rating (max from all components)3 = 95.7% <br /> Notes: <br /> 1) See additional documentation in"Appendix C-Software Analysis Output"for calculations supporting the%capacity listed. <br /> 2) See additional documentation in"Appendix D-Additional Calculations"for calculations supporting the%capacity listed. <br /> 3) Rating per TIA-222-H,Section 15.5. <br /> ENG-FRM-10208.
