New Research Report

Posted on by

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! Volumes II and III will be published in the next few months.

Fahnestock Delivers Dexter Lecture

Posted on by

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.

New Undergraduate Researchers
