About Zhengyu

Dr. Zhengyu Liu is a research engineer for the Bridge Engineering Center (BEC) and the Timber Bridge Program. He provides analytical expertise and project oversight for BEC projects. Dr. Liu has been involved in the conduct of bridge-related research for over eight years.

Dr. Liu received his master’s degree in civil engineering in 2014 and doctorate in structural engineering in 2018 from Iowa State University. Following the completion of his PhD, he continued his work at the Bridge Engineering Center as a research engineer. In total, he has contributed to more than 20 bridge-related research projects for numerous federal, state, and local agencies. His current research is in the general area of bridge engineering with specific interest in accelerated bridge construction (ABC), precast bridge element design and connection detailing, time-dependent bridge superstructure behavior, structural health monitoring and load rating, and highly nonlinear bridge structure simulation, etc. He is an author/co-author of more than 20 bridge structure related research reports and peer-reviewed journal articles.
