Analysis and Design of Steel Arch Bridges
by Thomas Murphy, Ph.D., P.E., S.E.
Senior Vice President, Chief Technical Officer, and Director of National Bridge Group at Modjeski and Masters
February 4th, 2026 | 3:30 PM ET to 5:00 PM ET | MJIS 1001
Registration Site: Steel Bridge Engineering Seminar Series
Seminar Overview: Arch bridges present unique challenges in their analysis and design, beyond those encountered when considering more typical multi-girder structures. This presentation will cover some of the key behaviors that need to be accounted for by a design engineer, starting from conceptual design, analysis considering stability and camber, and design of arch ribs, tie girders, and hanger systems.
