<br />introduction
<br />This report desgribes, illustrates, ind cxplams the Structural Calculation Packet for
<br />SnapNracks Series 100 Mounting System, dated 4/12/20]2. The calculations have been
<br />perfolmed in accordance with the 2012 Intcrnational Building Code (IBC). The racking
<br />system has been dcsigned to withstand code-lirescribed forces due zo its own weight, the
<br />weight of the boli pan,16, the snow loads, and both the wind and sell:mic forces.
<br />Rail Snans
<br />This rcpor[ covers two ditrcren; material options for the system rails. Although they ur
<br />both aluminum. one rail option uses a 6063 alloy (25 W yield) and Lhe other uses a 6005
<br />alloy (33 ksiyield)
<br />Despite having difrelent yield strengtht both typeb of ruils support the PV panels As for
<br />the tails themseli'cs. they are bupponed by mounting hardware which attaches them to Ihe
<br />roof structure with spans thai arc expressed in inches. Refer lo the tables below for rail
<br />spans under varying conditions of rail alloy and roof height. Shaded cclls require an edge
<br />zoncadjusimcm (sce dewils following charts).
<br />»tes for Tibles IA thru ZH
<br />1. Determine thc mean roof height. til[ angle. and mil alloy < i f you arc un5ure. m
<br />the 6063 alloy values) For me,n roof heighas less than 30 feel use Table IA,aA
<br />for till angles less ilan 19 degrees. Table 18/28 for lili angles between 20 806 36
<br />degrees, Table 10/2C for till angles between 37 and 45 degree, and Table 1 D/2D
<br />for ti[£ angles between 46 and 60 degrees. For mean roof heights between 31 and
<br />60 feet u/ Table IE/ZE for tilt angles less rhan 19 dog™ch. Table IF,21' for till
<br />angles between 20 and 36 degrees, Table 10/20 for till angles between 37 and 45
<br />degrees, and Table I HaH for tilt angles between 46 and 60 degrees
<br />2. Dclcnnine the wind and snow load for th project site Ihon, the building
<br />department. Make certain lo use 2012 IBC wind loads. Locate the wind load in
<br />the table across lop rows and me snow load down Ihe left columns lo find
<br />corresponding maximum rail span.
<br />3. For snow loads. column Pg equals the ground snow,
