(including mounting system) <br />Installed Area: 732.15 ft2 <br />Design Criteria: <br />C.B.C. 2010 <br />ASCE 7-05 <br />Design Methodology: <br />Per the exception in Section 3403.4 of the C. B.C. 2010: <br />"Any existing lateral load-carrying structural element whose demand-capacity ratio with the addition considered is no more than 10 percent greater than <br />its demand-capacity ratio with the addition ignored shall be permitted to remain unaltered" <br />This calculation will verify whether or not·the increased loads imposed by the addition, will result in an increase of 10% or less of a demand in <br />the existing structure. If ithe demand increase is within 10% of the original demand-capacity ratio, no retrofit shall be required. <br />10/21/2013 10:34 AM <br />\\peanasv2\Pool\Projects\2013\2165-13 Solar Panel - Residential\13-2165 SOLAR PANEL CALCS.xlsx <br />Page 7 of 13 <br />©Pool Engineering, Inc. 2013 <br />.
