(6)RRH units are to be mounted on a new H- <br /> frame al ground level. <br /> ANALYSIS: <br /> The purpose ot this analysis is to determine i(the existing tower is structurally adequate to support the proposed <br /> loadings.The tower has been analyzed in accordance with lhe 2009 International Building Code using lhe TIA- <br /> 222-G Structurel Standard for Antenna Supporting Structures and Antennas-Addendum 2. The addilional <br /> design crileria used in our analysis is as follows: <br /> . 85 mph (3-sec gus[)with no ice • Topographic Category 1 <br /> • 30 mph (3-sec gust)wilh 114"inch radial ice • Crest height of 0' <br /> . Wi�d Exposure B • 60 mph serviceability wind <br /> • Structure class II <br /> The analysis and modeling of lhe tower was performed using tnxTower v6.0.0.8.A 3-D finile element program <br /> specifically created for analyzing tower structures. <br /> RESULTS: <br /> Based on our review of the existing tower with lhe proposed panel antennas,we have determined the following: <br /> Element Status <br /> ` Existin Wood Pole: Structurall Ade uate 61% _� <br /> I Existing Pole Embedment: Structurall Ade uate 64% I <br /> Please refer lo Appendix A tor structural calculalions supporting lhe above resulls as well as lhe conclusions <br /> section below. <br /> We trust this addresses your concerns.
