January 31, 2024 <br />1.0 ft T-Arms Mount Analysis CCI BU No 825183 <br />Order 663380, Revision 1 Page 4 <br /> <br />ENG-FRM-10208, Rev. E <br />3.2) Assumptions <br /> <br />1) The antenna mounting system was properly fabricated, installed and maintained in good condition <br />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) The analysis will be required to be revised if the existing conditions in the field differ from those <br />shown in the above-referenced documents or assumed in this analysis. No allowance was made <br />for any damaged, missing, or rusted members. <br />5) Prior structural modifications to the tower mounting system are assumed to be installed as shown <br />per available data. <br />6) Steel grades have been assumed as follows, unless noted otherwise: <br /> Channel, Solid Round, Angle, Plate ASTM A36 (GR 36) <br /> HSS (Rectangular) ASTM A500 (GR B-46) <br /> Pipe ASTM A53 (GR 35) <br /> Connection Bolts ASTM A325 <br /> <br />This analysis may be affected if any assumptions are not valid or have been made in error. Trylon should <br />be notified to determine the effect on the structural integrity of the antenna mounting system. <br /> <br />4) ANALYSIS RESULTS <br /> <br />Table 3 - Mount Component Stresses vs. Capacity (T-Arms, All Sectors) <br />Notes Component Critical <br />Member Centerline (ft) % Capacity Pass / Fail <br />1, 2, <br />3, 4 <br />Mount Pipe(s) MP4 <br />56.0 <br />35.3 Pass <br />Standoff(s) M9 63.9 Pass <br />Mount Connection(s) - 20.6 Pass <br /> <br />Structure Rating (max from all components) = 63.9% <br />Notes: <br />1) See additional documentation in "Appendix C - Software Analysis Output" for calculations supporting the % capacity <br />consumed. <br />2) See additional documentation in “Appendix D – Additional Calculations” for detailed mount connection calculations. <br />3) All sectors are typical <br />4) Rating per TIA-222-H, Section 15.5 <br /> <br /> 4.1) Recommendations <br /> <br />The mount has sufficient capacity to carry the proposed loading configuration. No modifications are required <br />at this time. <br /> <br /> <br /> <br />2210 3%4 N Grand Ave Unit# <br />WCC01 - 1011184045/30/2024
