This scope includes modifying an <br /> existing door opening to a larger size. These calculations cover modifications to the exterior steel <br /> supports of the existing exterior metal panels. <br /> Wind girts were designed for wind loads specified within the design criteria section of these <br /> calculations. Please refer to the wind criteria of wind load calculations for components and cladding. <br /> Deflection criteria for revisions to the existing wind girds assumed the following: <br /> U240 maximum deflection <br /> LRFD Wind loads for deflection were reduced by a factor of 0.42 per IBC 1604.3 footnote f. <br /> C002 <br />
