Zhou Presents at IBC 2022
Congratulations to PhD candidate Sunny Zhou for presenting today at the International Bridge Conference in Pittsburgh! Sunny’s presentation, “Construction and Live Load Behavior of a Skewed Steel I-Girder Bridge,” describes a portion of the ongoing project “Evaluation of Spatial and Temporal Load Distribution in Steel Bridge Superstructures,” which is sponsored by the Illinois Center for Transportation. Accompanying the IBC presentation is a peer-reviewed paper in Transportation Research Record: Journal of the Transportation Research Board, which is now available online:

Paper on Frame-Spine-FLC Testing at E-Defense
In December 2020 – as part of the NSF-funded project “Collaborative Research: Frame-Spine System with Force-Limiting Connections for Low-Damage Seismic-Resilient Buildings” – researchers from the University of Illinois, Lehigh University, Oregon State University, Kyoto University, Hokkaido University and E-Defense conducted full-scale building earthquake simulations on the shake table at the Hyogo Earthquake Engineering Research Center (E-Defense). The four-story building employed a novel low-damage structural system and the building was furnished with hospital fixtures and equipment to evaluate protection of occupants and building contents. The testing program concluded on December 17 with an earthquake simulation using an input acceleration record from the 1995 Kobe Earthquake (100% JMA Kobe video linked). A paper that provides an overview of the testing program was presented at the 17th World Conference on Earthquake Engineering:
