New Report Published

A new research report, which partially documents a multi-year research project that included bridge field monitoring and numerical simulations of live load and thermal effects, is now published online. This work is funded by the Illinois Center for Transportation. Sunny Zhou and Ricardo Dorado, the Ph.D. students on the project, are recognized for their essential roles executing this complex campaign! Volume I was published earlier this year and Volume III will be published next month.

Spatial and Temporal Load Distribution in Steel Bridge Superstructures (Vol. II): Evaluation of Skewed Steel I-Girder Bridge Behavior under Deck Placement and Live Load through Field Monitoring and Numerical Simulation

Tao Passes Prelim

Congratulations to Zhuoqi Tao on passing the Ph.D. preliminary exam last week! Zhuoqi’s research on steel moment resisting frames with spines and force-limiting connections for enhanced seismic performance is partially funded by the National Science Foundation.

Ibrahim Defends Dissertation

Congratulations to Ahmed Ibrahim for defending his Ph.D. dissertation last week! Ahmed’s doctoral research, Automated Inspection and Assessment of Damaged Steel Girders Using Computer Vision and Machine Learning, was supervised by Ahmed Elbanna, Larry Fahnestock and Jim LaFave. Ahmed’s research was part of the project Strength and Serviceability of Damaged Steel Girders, which is funded by the Illinois Center for Transportation.

Fahnestock Delivers Dexter Lecture

Last month Larry Fahnestock delivered a Dexter Memorial Lecture, part of the Warren Distinguished Lecture Series, in the Department of Civil, Environmental, and Geo- Engineering at the University of Minnesota. The Dexter Memorial Lecture is held to honor the legacy of Prof. Robert Dexter (1956-2004). Robert is remembered for his technical expertise and contributions in steel fatigue and fracture, and for his humility, kindness, generosity and encouragement that touched so many people.
