Understanding the energy transfer mechanism in the near field of impact driven piles (2018)
Conference Proceeding
Gkrizi, A., Athanasopoulos-Zekkos, A., & Woods, R. D. (2018). Understanding the energy transfer mechanism in the near field of impact driven piles

Pile installation by applying an impact to the top of a pile appears to be a simple construction process but analysis of that process is complicated as it involves a source of energy, the structural member (pile), and the ground... Read More

Pile driving vibration attenuation relationships: overview and calibration using field measurements (2018)
Journal Article
Gkrizi, A., Athanasopoulos-Zekkos, A., & Woods, R. D. (2018). Pile driving vibration attenuation relationships: overview and calibration using field measurements. Geotechnical Special Publications, 435-444. doi:10.1061/9780784481479.045

Empirical equations to predict ground motions during construction operations have been suggested by various researchers. These empirical correlations were developed after measuring particle velocities on the ground surface during pile installation or... Read More

H-pile driving induced vibrations: reduced-scale laboratory testing and numerical analysis (2018)
Journal Article
Grizi, A., Athanasopoulos-Zekkos, A., & Woods, R. D. (2018). H-pile driving induced vibrations: reduced-scale laboratory testing and numerical analysis. Geotechnical Special Publications, 165-175. doi:10.1061/9780784481585.017

Ground vibrations due to impact pile driving operations can become a major concern when affecting nearby structures and underground utilities. In an effort to better understand the transmission and dissipation of energy into the ground during impact... Read More

The May 25th 2011 railroad embankment failure in Ann Arbor, Michigan, as a means for teaching geotechnical engineering (2016)
Journal Article
Zekkos, D., Athanasopoulos-Zekkos, A., Grizi, A., & Greenwood, W. (in press). The May 25th 2011 railroad embankment failure in Ann Arbor, Michigan, as a means for teaching geotechnical engineering. doi:10.4417/IJGCH-03-04-03. ISSN 1790-2045

A 30-m long railroad embankment failure that occurred on May 25 2011 in the city of Ann Arbor, Michigan, is presented. Emphasis is given on the field observations of the failure, the characterization of the site conditions and the seepage and slope s... Read More

Response of municipal solid waste to mechanical compression (2016)
Journal Article
Zekkos, D., Fei, X., Grizi, A., & Athanasopoulos, G. (2017). Response of municipal solid waste to mechanical compression. Journal of Geotechnical and Geoenvironmental Engineering, 143(3), doi:10.1061/(ASCE)GT.1943-5606.0001608. ISSN 1090-0241

The compressibility of municipal solid waste (MSW) is of engineering interest as it affects the short-term and long-term performance of landfills, as well as their expansion, closure, and postclosure development. An assessment of the field settlement... Read More

Ground vibration measurements near impact pile driving (2016)
Journal Article
Grizi, A., Athanasopoulos-Zekkos, A., & Woods, R. (2016). Ground vibration measurements near impact pile driving. Journal of Geotechnical and Geoenvironmental Engineering, 142(8), doi:10.1061/(ASCE)GT.1943-5606.0001499. ISSN 1090-0241

Pile driving is a complex dynamic process where little insight has been garnered in terms of the energy transfer from the driver to the soil and surrounding structures. Ground motion measurements during driving of full scale steel H-piles with diesel... Read More

Measurement of ground motion near piles during driving (2014)
Journal Article
Woods, R., Athanasopoulos-Zekkos, A., Gkrizi, A., Pietrangelo, A., & Zimmerman, A. (in press). Measurement of ground motion near piles during driving. Geotechnical Special Publications, doi:10.1061/9780784413265.041. ISSN 0895-0563

Two types of vibration damage caused by driving piles have been reported in the literature: direct structural damage and damage due to settlement. Direct damage results from vibratory excitation of structures at amplitude exceeding the structural tol... Read More
