Bridging the Gap at the 4th International Bridge Seismic Workshop
Kumar Ghosh, PhD, TYLin Principal Bridge Engineer, presented the paper, “Bridge the Gap Between Academia and Industry – A Case Study of Column Base Pinned Connections” at the prestigious 4th International Bridge Seismic Workshop held at Carleton University at Ottawa, Ontario, Canada. The paper and presentation demonstrate how the synergy between academia, departments of transportation, and the industry is critical to fostering a unique crossdisciplinary exchange.
This paper discusses one such collaboration in a high seismic region: the implementation of pinned (twoway hinge) connections between concrete bridge columns and large-diameter drilled shafts to limit overstrength moment and shear while transferring axial load for the award-winning West Mission Bay Drive Bridge in San Diego, California.
The paper was co-authored by Dr. Ghosh, Dr. Amir Malek, California Department of Transportation Senior Bridge Engineer and Specialist, and Dr. M. “Saiid” Saiidi, Foundation Professor of Civil & Environmental Engineering, Emeritus, University of Nevada, Reno, and world-renowned researcher in the field of earthquake engineering.
