Geotechnical Earthquake Engineering Colloquium: Final Report   [open pdf - 2MB]

"There have been many major advances in geotechnical earthquake engineering since research was accelerated by the 1964 Alaska and Japan earthquakes, where much of the damage was caused by soil effects. However, in many respects the state of the art remains less than satisfactory. A number of questions with important safety and economic implications have never been answered, or even posed clearly. Recent advances in computer and information sciences, laboratory and field testing capabilities, and field observation of earthquake effects, all infused with a new generation of powerful sensing technologies, provide an opportunity for resolving many of these major problems. Specifically, analytical procedures for geotechnical analysis and design, including powerful computer simulations, show promise of providing an increasingly realistic virtual counterpart to the actual performance of soils and structures during earthquakes. They also make it possible to perform systematic quantitative observational and experimental validations of those procedures. On July 29, 2009, a workshop (colloquium) was convened jointly by the Center for the Study of Natural Disasters, Coastal Infrastructure and Emergency Management of the University of North Carolina at Chapel Hill, and the Center for Infrastructure and Transportation Studies of Rensselaer Polytechnic Institute, to identify high priority research questions that may now be addressed with modern technological and analytical tools. The workshop was held at Rensselaer Polytechnic Institute in Troy, NY. The workshop participants are identified in Appendix A. The participants considered the range of successes and problems in the field, identified groups of facilities exposed to earthquake risk that are of concern to the Department of Homeland Security, and prepared a prioritized list of research areas that can improve the state of practice for these facilities."
