I thought that might be the case, always interesting to see different methods that become common in different regions! That is also my line of thinking, L/180 keeps the limit to approx 9mm for a 1.6m long sleeper bay and that number sits well with me Appreciate the reply, helps confirm I'm...

Sure, not a cross section but an image of the typical construction. (see below) very common for residential subdivisions in QLD. Soldier pile steel post with concrete sleeper lagging. I'm not worried about steel post deflection, I've got a limit there I'm happy with; just the sleepers between...

Hi All Doing a design for concrete sleeper retaining walls, pretty comfortable with most of the design But I am curious what deflection limits you've used for concrete sleepers. AS 3600 gives a limit of L/250 for concrete elements, but AS 3600 is intended mostly for building structures. ACI...

Hi All; sorry for the late reply to this. Notifications for it were diverted to spam automatically. So I did not realise. To quickly respond; F-D Does Cp just stand for arching in pile? I do allow for this but I use 0.08*phi and limit it to 3. I dont normally apply arching to kp though, rather...

I've recently designed some soldier pile/ concrete sleeper retaining walls using Brom's method. Using Coulombs equation for passive pressure and allowing for a wall friction angle of 0.5*Phi gives a much higher kp value than Rankine's. Based on a previous topic Here I gathered allowing for wall...
