July 20, 2021 14.5 ft. Platform Mount Modification CCI BU No. 826263 Project Number 92189.006.01, Order 565138, Revision 0 Page 4 A tool internally developed by B+T Group, was used to calculate wind loading on all appurtenances, dishes and mount members for various loading cases. Selected output from the analysis is included in Appendix B "Software Input Calculations". This analysis was performed in accordance with Crown Castle's ENG-SOW-10208 Tower Mount Analysis (Revision D). In addition, this analysis is in accordance with AT&T's Mount Technical Directive —R15. Manufacturer's drawing were used to create the model. 3.2)Assumptions 1. The antenna mounting system was properly fabricated, installed and maintained in good condition in accordance with its original design, TIA Standards, and/or manufacturer's specifications. 2. The configuration of antennas, mounts, and other appurtenances are as specified in Table-1. 3. All member connections are assumed to have been designed to meet or exceed the load carrying capacity of the connected members unless otherwise specified in this report. 4. Mount areas and weights are determined from field measurements, standard material properties, and/or manufacturer product data. The following assumptions have been included in the analysis of the mount: Component Section Length Note Mount Pipe 2" Std. Pipe 10'-0" In All Position Raycap Pipe 2" Std. Pipe 4'-0" - Raycap Pipe 2" Std. Pipe 5'-0" - 5. Serviceability with respect to antenna twist, tilt, roll or lateral translation is not checked and is left to the carrier or tower owner to ensure conformance. 6. All prior structural modifications, if any are assumed to be correctly installed and fully effective. 7. The analysis will be required to be revised if the existing conditions in the field differ from those shown in the above-referenced documents or assumed in this analysis. No allowance was made for any damaged, missing, or rusted members. 8. The following material grades were assumed (Unless Noted Otherwise): (a) Connection Bolts : ASTM A325 (b) Steel Pipe : ASTM A53 (GR. 35) (c) HSS (Round) : ASTM 500 (GR. B-42) (d) HSS (Rectangular) : ASTM 500 (GR. B-46) (e) Channel :ASTM A36 (GR. 36) (f) Steel Solid Rod :ASTM A36 (GR. 36) (g) Steel Plate : ASTM A36 (GR. 36) (h) Steel Angle : ASTM A36 (GR. 36) (i) UNISTRUT : ASTM A570 (GR. 33) This analysis may be affected if any assumptions are not valid or have been made in error. B+T Group should be notified to determine the effect on the structural integrity of the antenna mounting system.
