Title: Seismic Evaluation of Concret Bridges in the Northeast
Author(s): Eric Thorkildsen, Roy A. Imbsen
Publication: Concrete International
Appears on pages(s): 33-35
Abstract:Bridge owners in the northeast region of the country have begun to evaluate some of their aging concrete structures for resistance to seismic loads. This usually occurs in conjunction with a proposed structural rehabilitation, such as a deck replacement. As a firm that specializes in the seismic evaluation of bridges, Imbsen Consulting Engineer has had the unique opportunity to assess several concrete bridges in this region of low to moderate seismic activity. Every bridge, especially those of concrete construction, has certain structural characteristics that enable it to resist some level of lateral loading. By using state-of-the-art techniques, such as lateral strength push-over type analyses, this can be brought forth in determining the ultimate capacity of a concrete element.
