Description

The South Dakota Department of Transportation (SDDOT) allows the use of precast double-tee bridges in counties because they are economical and fast in construction. Alternative durable prefabricated bridge systems are needed to provide more options to local governments. The present study was carried out to investigate the feasibility of alternative prefabricated bridge systems that can be incorporated in SD and other states.

This presentation will discuss the research findings and how to best implement the strategies tested for successful implementation in our areas.

Speaker(s)

Dr. Mostafa Tazarv is an assistant professor in the department of Civil and Environmental Engineering at South Dakota State University (SDSU). Prior to joining SDSU in 2015, Dr. Tazarv was a post-doctoral scholar at the University of Nevada, Reno, where he also received his Ph.D. His research interests include the behavior of concrete structures, advanced materials for civil infrastructure, accelerated bridge construction, and large-scale testing. Dr. Tazarv is currently working on different research projects as PI and Co-PI with a total funding exceeding $2.1 million. His past research led to the development of a new generation of bridges that can be built faster, last longer, perform better in severe events, and cost less in long-term. The first shape memory alloy (SMA) bridge in the world was constructed in Seattle, in which design and construction guidelines were based on his study on advanced materials. The unique aspect of this bridge is its continuous functionality after severe events with minimal damage and repair needs. Furthermore, his large- and full-scale testing of bridges and buildings resulted in new design alternatives for the State of South Dakota and its local governments to save millions of dollars in bridge replacement, maintenance, and performance. He also invented a new connection for concrete structures to expedite construction and to quickly repair these structures after a severe event such as earthquake or hurricane.

Target Audience

This presentation is for all structures, materials, and design staff in both state and local governments. Decision makers for structure repairs, replacement or installation should also attend. This research is practical and is being used in SD. Attendees will receive immediate information to implement and incorporate in their bridge programs.
