Abstract:As a resource for researchers and practitioners focused on the seismic performance of major civil infrastructure, including surface and maritime transportation systems, the project team has developed a large, publicly accessible database of static, cyclic, and post-cyclic laboratory test data for predominantly silt-rich (transitional) soils with properties and dynamic behaviors typically lying between, or transitioning from, “sand-like” behavior and “clay-like” behavior. Silt-rich soil deposits are prevalent in the Pacific Northwest, and in regions of British Columbia and Alaska. This database has been established with laboratory data and supporting documentation from geotechnical project reports and applied research investigations for soil units primarily located within these three regions, and supplemented to a lesser degree with data from other regions. The collection of laboratory test data, supporting documentation, and meta-data are curated by the second author at the Department of Civil & Environmental Engineering, Portland State University and managed as a “living data repository” that is being continually updated with new data from projects throughout the Pacific Northwest.
