Seismic Damage State Models for Oregon Bridges

Frequently traveled parts of Oregon are within the seismically active Pacific Northwest, and many of the bridges were designed and built to lateral demands that were assumed to be less than the current expectation, a deficiency caused by our growing awareness of seismic hazard and our enhanced understanding of the non-linear response of bridges. This vulnerability to da... Read More
