ENGINEERED POWER SOLUTIONS <br />72 SOUTH MAIN STREET, SUITE A <br />TEMPLETON, CA 93465 <br />Solar Warehouse Rail Analysis – Generic Packet <br />3.5 – Rail Load Summary <br />The governing compression (downward) loads at the anchors are from one of multiple <br />load combinations. The governing load combination is dependant on the specific <br />design parameters but the govering copression load combination will be from one of <br />the following load combinations per Section 2.4.1: <br />▪ ASCE 7-16: <br />▪ D <br />▪ D+S <br />▪ D+0.6W <br />▪ D+0.75S+0.75(0.6W) <br />Example Scenario Calculation: <br />o Compressive loads: <br /> D: 8.3 plf <br /> S: 81.9 plf <br /> W: 32.2 plf <br /> <br /> D+S: <br /> = 8.3 plf. + 81.9plf = 90.2 plf <br />D+0.6W <br /> = 8.3 plf. + 0.6(32.2 plf) = 27.6 plf <br />D+0.75S+0.75(0.6W) <br /> = 8.3 plf. + 0.75(81.9 plf) + 0.75*(0.6*32.2plf) = 84.2 plf <br />➔ Therefore use 90.2 plf compression load for typical rail. <br />The following pages provide the rail analysis results for the example case (loads for <br />Wind Zone 1 shown). The Rail spans are shown on the first sheet and are in ½ foot <br />increments. <br /> [A similar rail analysis has been calculated for each separate case detailed in the <br />tables (not shown in this packet)] <br />Page 70 <br />2004 W Picasso - <br />2018062008/29/23
