It is the carrier's responsibility to ensure compliance to the structural <br /> limitations of the existing and/or proposed antenna mounts. TEP did not perform a site visit to <br /> verify the size, condition or capacity of the antenna mounts and did not analyze antennas <br /> supporting mounts as part of this structural analysis report. <br /> 7) The following material grades were assumed: <br /> a) Tower legs:ASTM A53-B-46 <br /> b) Tower bracing:ASTM A36 <br /> c) Anchor rods:ASTM A615-75 <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 /> tower. <br /> 4)ANALYSIS RESULTS <br /> Table 5-Section Capacity(Summary) <br /> Section' " ?
