This is yet another paper which cited my work, in this case the ZWAVE paper. Once again I'm not sure why they picked this one; it's probably because I explored a soil model based on that of Randolph and Simons (1986), which they also cited and discussed. I came back to models like this in … Continue reading Comments on “A novel soil reaction model for continuous impact pile driving”
He's gone home: Dr. Lee Leon Lowery, Jr., known as “L3” to his students, passed away on February 28, 2024. He spent his lifetime learning from the world around him and in return teaching the world around him.... Dr. Lowery was a man of great intellect, generosity, and wit. He gave of himself wholly and … Continue reading RIP Lee L. Lowery, Jr.
More Resources Foundation Design and Analysis: Deep Foundations, Driven Pile Bearing Capacity (for ASD Methods) Foundation Design and Analysis: AASHTO LRFD Method Design and Construction of Driven Pile Foundations, 2016 Edition. This topic is spread out between the two volumes. Overview Engineers have always designed structures with uncertainty in mind, thus it is not permissible … Continue reading Driven Pile Design: ASD and LRFD Methods
MORE RESOURCES Foundation Design and Analysis: Deep Foundations, Pile Dynamics Design and Construction of Driven Pile Foundations, 2016 Edition. The second volume covers this topic. It should be obvious that the state of our predictive methods should make verification necessary for deep foundations, and that is certainly the case. One type of verification already discussed … Continue reading Driven Pile Design: Inverse and Verification Methods
More Resources Foundation Design and Analysis: Deep Foundations, Pile Dynamics Design and Construction of Driven Pile Foundations, 2016 Edition. The second volume covers this topic. Overview Now we come to the topic that was the genesis of this and the related sites: pile dynamics. There's quite a lot on the subject, so an extensive review … Continue reading Driven Pile Design: Wave Equation Analysis
More Resources Foundation Design and Analysis: Deep Foundations, Lateral Loading of Piles Design and Construction of Driven Pile Foundations, 2016 Edition. Having looked at axial loads on driven piles, we come to the subject of lateral loads on driven piles. Deep foundations in general are more suitable for lateral loads than shallow ones, so this … Continue reading Driven Pile Design: Lateral Loads on Piles
More Resources Foundation Design and Analysis: Deep Foundations, Driven Pile Settlement and Group Capacity Design and Construction of Driven Pile Foundations, 2016 Edition, Volume I covers the topics discussed in this post, and does so in more detail, you need to look at this if you're serious about this topic. Overview As a general rule, … Continue reading Driven Pile Design: Axial Group Bearing Capacity and Settlement
In the previous post we looked at the various ways of computing the "bearing capacity" of the pile. We also made the case that "bearing capacity" wasn't a really accurate way of characterising the load bearing performance of a driven pile. In this post we will address both of these issues and show the most … Continue reading Driven Pile Design: Static Load Testing and Axial Settlement
As mentioned earlier, it would be a long business to catalog all of the methods that have been devised to estimate the axial bearing capacity (with all of the problems of that concept) of driven piles. Here we will show how three of these methods apply to our test case (reproduced below.) More Resources Foundation … Continue reading Driven Pile Design: Three Methods of Analysis
More Resources Foundation Design and Analysis: Deep Foundations, Driven Pile Bearing Capacity Design and Construction of Driven Pile Foundations, 2016 Edition, Volume I covers the topics discussed in this post. Before I get into the actual estimation (and estimation is the operative word here) of axial capacity, I need to make some important observations, as … Continue reading Driven Pile Design: Axial Loads, General Considerations
