Soldier Piles & Lagging using SPW911 and LRFD Soldier Piles & Lagging using SPW911 and LRFD Madmax52 (Structural) (OP) 10 Aug 16 13:04 I'm trying to design a soldier pile and lagging wall using SPW911 but can't figure out how to use it for LRFD. Does anyone have a suggestion? RE: Soldier Piles & Lagging using SPW911 and LRFD PEinc (Geotechnical) 10 Aug 16 20:15 Yes. Buy a different design program (CivilTech Software's Shoring Suite) or do it by hand. www.PeirceEngineering.com RE: Soldier Piles & Lagging using SPW911 and LRFD Madmax52 (Structural) (OP) 10 Aug 16 21:09 Yes, we're looking into some new software but I was hoping to be able to use the software that we have because it's crunch time. Thanks RE: Soldier Piles & Lagging using SPW911 and LRFD umrce (Structural) 11 Aug 16 13:05 Unfortunately PEinc answer is probably the best you're going to hear. SPW911 is not capable of LRFD design. The best you might be able to do is develop a semi-handcalc aapproach and see if you could copy the analysis output from SPW911 in an excel format, factor the loads and do your design checks. While I'm throwing that idea out, I'm not sure I would recommend it or that it would even work since you're embedment is an iterative process based on your loads. As you factor them it's going to impact your depth and you'll probably need a spreadsheet that basically does everything SPW911 does. This would probably be more prone to error and less reliable (not to intentionally insult you're excel capabilities!) than a program that has been developed and proven in commercial use.
