Effects of pile-driving induced vibrations on nearby structures and other assets.

This project is focused on better characterizing pile-driving induced vibrations and understanding their attenuation. Emphasis is given on quantifying the effect of soil type, hammer and pile combination and number of cycles on the soil settlement. This is achieved by a combination of field testing measurements and 3D finite element numerical analyses, to develop vibration…

Seismic isolation of earth retaining structures using EPS-Geofoam compressible inclusions.

The objective of this project is to study the effectiveness of an EPS geofoam compressible inclusion as a seismic isolator against seismic lateral pressures. Twocentrifuge testshave been performed on small scale physical models of retaining structures with and without EPS compressible inclusions, generating the first centrifuge data that highlight the seismic isolation capabilities of the…

Ground motion selection and modification criteria for the seismic design of earthen levees and other geotechnical infrastructure.

In this research project, ground motion intensity measures that are critical for predicting levee response have been established. The variability of levee response in terms of soil liquefaction triggering and seismic slope stability has been investigated and regressions have been developed to serve as guidelines for selection of ground motions for levee embankments.

Development of a GIS-based tool and methodology to evaluate the seismic risk in regions protected against flooding by earthen levee systems.

This project focuses on developing a decision-making methodology that helps users prioritize mitigation efforts and predict levee system performance for selected seismic event scenarios.The proposed methodology will track uncertainties associated with (1) levee geometry, soil stratigraphy and soil properties, (2) the interpolation method, and (3) the calculation of the joint probability of failure due to…

Professor Athanasopoulos-Zekkos featured in MDOT Research Spotlight

Assistant Professor Adda Athanasopoulos-Zekkos is the principal investigator of a project that was featured in a Michigan Department of Transportation (MDOT) Research Spotlight. The story, titled, "Minimizing the effects of pile driving vibrations", describes piles, which are steel or concrete shafts that are driven into the ground during construction using large mechanical hammers. These piles…
