The structure has been analyzed in accordance with the 2009 International <br /> Building code, The additional design criteria used inour analysis ioaofollows: <br /> ° 86mph C3-soogust) ° Occupancy Category U <br /> ° Wind Exposure B ° Seismic Design Category D <br /> ° Topographic Factor, Kt= 1.O ° SDS = O.845. So1 = 0.460 <br /> RESULTS/ <br /> | <br /> Existing Roofs: Structurally Adequate ! <br /> Skylight Framing: � <br /> � <br /> Please refer to calculations for structural analysis supporting the above results as well as the conclusions � <br /> section below for additional comments. � <br /> VVetrust this addresses your concerns. Please contact uuifthere are any questions. <br /> CONCLUSION: <br /> To the best of our knowledge and belief, the existing structure with the proposed loading as listed in ` <br /> above ieinsatisfactory compliance with the requirements of the specifications, codes and agencies � <br /> having jurisdiction over the work. <br /> Tt � ! <br /> ' <br /> , <br /> 1 <br /> ` <br /> � <br /> PropuredBy EhkEvenson.
