Research Highlights
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...

ODOT Understanding Pedestrian Injuries and Social Equity
Nathan McNeil
Portland State University partnered with the project PI Josh Roll of the Oregon Department of Transportation on a two-phase research project examining pedestrian injury and social equity. Past research and planning has highlighted the existence of pedestrian injury disparities throughout the US and some local agencies have performed cursory analysis in Oregon. However, no statewide analysis of pedestrian injuries in Oregon has been completed to see how these injury outcomes differ by race and...
