    Pile Capacity

    Ben, Thanks. Oh the puns lol. Yea I was finally happy that FHWA came out with a new Driven Pile manual, took them a while. I'm using the Nordlund method for an HP 14x73. I did look at settlement and I'm good there, so no Downdrag. I guess for me, I'm usually designing Bridge Abutments and...

    Pile Capacity

    I had a question about determining Pile Capacity. I'm using the Nordlund Method for Driven Piles to determine the skin and tip resistance. In most cases when designing a bridge Abutment, as a conservative approach I usually take the bottom of footing as the top of the ground (usually the...

    Driven Piles for foundation onto Rock

    For driving through rock or just skin resistance in general, I made a comment about it and will wait to see the response. Dynamic Testing will be performed. The plans show a minimum penetration elevation, based on scour, settlement, fixity and lateral movement (I think that's all). Then there...

    Driven Piles for foundation onto Rock

    Sorry, let me clarify a little bit. The project that is being designed is a Bridge, and the Bridge abutment will be on HP piles currently. This is just the design phase of the project. I'm not sure if it was a geotechnical engineer or not. Trying to be a little vague, but mainly we are...

    Driven Piles for foundation onto Rock

    I am currently reviewing a design from another company and was wondering if anyone could help with finding a good Foundation Book on Rocks. I am a Structural Engineer, but we design our own foundations, using the AASHTO LRFD code, so I'm well versed when it comes to Driven Piles and Drilled...

    Development Length error in AASHTO LRFD Bridge 7th Edition

    Thank you BridgeEI. The page that contained λrc was misplaced, that's what made a HUGE difference.

    Development Length error in AASHTO LRFD Bridge 7th Edition

    Is there a development length error in the AASHTO LRFD Bridge 7th Edition (which includes 2015/2016 Interim Revisions?). I'm getting a much longer development length (6') as compared to the previous equation before the interim revisions (1') for a #5 bar. Is this correct? Or is there an error?
