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… Read More

Past eco-driving research has looked at the effectiveness of various eco-driving programs, but the role supervisor and organizational support have remained unexamined. This is unfortunate, as support from the supervisor and the organization have consistently been shown to determine whether or not employee interventions (e.g., training, safety) are effective (e.g., Christian et al. 2009; Salas et al., 2012). In other words, supervisor and organizational support are important for translating… Read More
