(3) Site Pro 1 Stacked 10'-10" T-Arms - Structural Evaluation Site USID #: 214755 3/1/2023 Page 3 of 4 ANALYSIS METHOD RISA-3D (Version 17.0.4), a commercially available analysis software package, and hand calculations were used to create a three-dimensional model of the mount and calculate member stresses for the proposed loading configuration. Selected calculations from this analysis are included in Appendices B & C. The following table details the information provided to complete this structural analysis. This analysis is based solely on this information.

This analysis is from information supplied, and therefore, its results are based on and are as accurate as that supplied data. GPD has made no independent determination, nor is it required to, of its accuracy. The following assumptions were made for this structural analysis. 1. The mount member sizes and shapes are considered accurate as supplied. The material grade is as per data supplied and/or as assumed based on experience with similar mounts. 2. The antenna configuration is as supplied and/or as modeled in the analysis. When information was not provided, the configuration was modeled based upon past experience with similar loading. 3. Some assumptions are made regarding antennas and mount sizes and their projected areas based on best interpretation of data supplied and of best knowledge of antenna type and industry practice. 4. The mount has been properly maintained in accordance with TIA Standards and/or with manufacturer’s specifications. 5. All welds and connections are assumed to develop at least the member capacity unless determined otherwise and explicitly stated in this report. If any of these assumptions are not valid or have been made in error, this analysis may be affected, and GPD should be allowed to review any new information to determine its effect on the structural integrity of the mount. 4111 3%4 S Main St Unit #WCC0112/13/2024
