Research Highlights

Application of LRFD Principles for Deep Foundations in Oregon: Phase 1

Trevor Smith
Peter Dusicka
Project Sponsor Champion: Bruce Johnson, ODOT State Bridge Engineer . The Oregon DOT has routinely relied on the use of the Wave Equation Analysis of Piles (WEAP) software to dynamically model the bridge pile driving installation operation. Either from the end of initial driving (EOID) when the pile reaches design penetration, or a later Beginning of Restrike (BOR) by the driving hammer, the ODOT has become proficient at establishing axial capacity based on WEAP results. This removed the ... Read More

Pedestrian Observation and Data Collection Curriculum

Jennifer Dill
The purpose of this project is to develop two class exercises suitable for undergraduate and/or graduate students in courses related to travel behavior, traffic safety, urban planning and design, or civil engineering. Initially, this project will focus on developing pedestrian-focused exercises that includes elements of both traditional traffic counts and behavioral components, the latter of which are often lacking from current data collections efforts. The first exercise will likely be count... Read More
