Geotechnical software company GEOSLOPE is offering a free webinar series on their GeoStudio software. This free, one-time-only, series provides training similar to their paid workshops for SLOPE/W and SEEP/W. The webinar sessions will be once […] The post GeoStudio Fundamentals Webinar Series appeared first on GeoPrac.net.
Inverse Analysis of Driven Pile Capacity in Sands
This is a new paper on the STADYN project. You can download it here. The abstract is as follows:
Methods of estimating the capacity of driven piles from dynamic pile top data have been well established for many years. The STADYN program uses a finite element methodology that is different from those currently in use. In this paper this program is applied to a well documented pile scenario of concrete piles driven into predominantly cohesionless soils. The pile top force-time and velocity-time history is applied to the model and the results compared with both dynamic tests using conventional methods and static load test results. The results are mixed; the dynamic results compare well with CAPWAP but other factors suggest that more work needs to be done on the STADYN model.
The conference that this was scheduled to be presented at was cancelled in view of COVID-19, so I created a “voice over PowerPoint” presentation. You can listen to it here:

Note: this is the first video presentation I did for this course when the COVID emergency hit in March 2020. There were many more for this and my other courses, some of which led to this award in 2021. The material I teach has changed since I made this video.
