Appurtenances will have a 154'rad cenfer. <br /> ANALYSIS: <br /> The purpose o!this analysis is to determine Nthe existing 6aflast trame is structurally adequate to support the <br /> proposed loadings and provide any recommendations(or modi(cation in order to 6ring the shvcture into <br /> compliance if needed. The structure has been analyzed in accordance w'rth the 2009 Intemational Bullding <br /> code. The additional design criteria used in our analysis is as(ollows: <br /> . 85 mph(3-sec gust) • Occupancy Category 111 <br /> . Wind[xposure B • Seismic Design Category D <br /> • Topographrc Factor, K:= 1.0 <br /> RESULTS: <br /> Based on our review o(fhe existir,g shuctwe wifh the proposed loadings, we have determined the following: <br /> Reinforced Ballast Frame: Structurall Ad uate with recommend modifications <br /> Existing Roof Structure: Structurall Ade uate <br /> Please re(er fo Appendix A for structural calculations suppoRing the above resufts as well as section 3 below for <br /> fhe modification recommendations. <br /> We trust this addresses your concerns.
