(including mounting system) <br />Installed Area: 229.98 ft2 <br />Design Criteria: <br />C.B.C. 2013 <br />ASCE 7-10 <br />Design Methodology: <br />Per the exception in Section 3403.4 of the C.B.C. 2013: <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 />3/20/2014 2:47 PM <br />\\peanasv2\Pool\Projects Solar\2014\0457-14 Residential\14-0457 SOLAR PANEL CALCS.xlsx <br />Page 7 of 13 <br />©Pool Engineering, Inc. 2014
