The installation has been analyzed in accordance with the 2012 International Buiiding Code. The following <br />parameters were used for lateral analysis: <br />Wind Speed: 110 mph (3 sec gust) <br />Wind Exposure: B <br />Topographic Factor, kzt: 1 <br />Occupancy Category: III <br />Seismic Design Category: D <br />Mapped Parameter, Ss: 1.315 <br />Mapped Parameter, S1: 0.499 <br />This Structural Analysis Report for the proposed AT&T Mobility equipment is inclusive of the entire equipment support <br />structure. This analysis is based on the specific assumptions and conditions as stated within the following report. <br />RESULTS: <br />Based on our review of the existi <br />,�, �., _ <br />Existing Antenna Mounts <br />Existinq Ballast Sled <br />structure with the <br />74.90% <br />100% <br />loadinas. we have determined the followi <br />Structurally Adequate / Designed per Code <br />Structurallv Adequate / DesiQned per Code <br />Please refer to Appendix A for structural calculations supporting the above results as well as the required modifications <br />and conclusions sections below for additional comments. _. ��. _ <br />We trust this addresses your concerns.
