Accessing Opportunities for Household Provisioning Post-COVID-19
Kelly Clifton
Kristina Currans , Amanda Howell
When the COVID-19 pandemic first swept across North America and led to emergency shutdowns during the spring of 2020, the way people acquired food and household necessities was dramatically impacted. As stay-at-home orders minimized personal travel, transit services were reduced and many stores and restaurants either closed or modified their operations.
This NITC grant expanded the scope of the NSF grant (https://trec.pdx.edu/research/project/1445) to allow for data collection in Oregon a...

Bridge Pile Foundations Subjected to Liquefaction-Induced Lateral Spreading
Arash Khosravifar
The overall goal of this research is to improve the seismic safety and resiliency of highway bridges in the Pacific Northwest during earthquakes. Past earthquakes have shown that liquefaction-induced lateral spreading can be a major cause of collapse for pile foundations. Bridge engineers generally agree that pile foundations must be designed for: (a) lateral spreading loads caused by liquefaction of soils adjacent to piles, and (b) inertial loads during shaking resulting from the superstruct...
