SSSBA Publishes New Research Report in Innovative Press-Brake-Formed Steel Tub Girder Bridge Technology Series

July 2, 2019

WASHINGTON D.C. — The Short Span Steel Bridge Alliance (SSSBA) has added a new research report to its series on the development and experimental testing of an innovative bridge system. The new report, “Volume VI: Field Performance and Rating Evaluation of a Modular Press-Brake-Formed Steel Tub Girder With a Steel Sandwich Plate Deck,” is available for free download at https://www.shortspansteelbridges.org/learning-center/research

The new study presents results from the experimental testing and analytical modeling of the Cannelville Road Bridge currently in service in Muskingum County, Ohio. The structure is composed of two modular, tub girder and sandwich plate steel (SPS®) deck units that were constructed offsite and erected using accelerated bridge construction (ABC) methods. It is the first press-brake-formed steel tub girder bridge to be erected with a composite SPS® deck system. 

“Test results from the Cannelville Road Bridge show that current AASHTO LRFD Specifications for analyzing shallow press-brake-formed tub girders are conservative, with field performance exceeding the calculated performance,” said Rich Tavoletti, director of the Short Span Steel Bridge Alliance. “This is great news for bridge owners, engineers and designers who are facing increasing demand for rapid infrastructure replacement since these bridges are cost-effective, practical for ABC applications, can last over 100 years, and are compatible with various deck designs as modular units.”

Tavoletti said that press-brake-formed steel tub girder bridges are ideal for replacing structures with spans up to 60 feet and that these bridges are currently being built or in service in Iowa, Ohio, Michigan, Texas and West Virginia. 

The Cannelville Road Bridge research is Volume VI in the “Development and Experimental Testing of Press-Brake-Formed Steel Tub Girders for Short Span Bridge Applications” series which are all available for free download at https://www.shortspansteelbridges.org/learning-center/research. The full series includes:

  • Volume I – “Development and Feasibility Assessment of Shallow Press-Brake-Formed Steel Tub Girders for Short Span Bridge Applications”
  • Volume II – “Experimental Evaluation of Non-Composite Shallow Press-Brake-Formed Steel Tub Girders”
  • Volume III – “Evaluation of Modular Press-Brake-Formed Tub Girders With UHPC Joints”
  • Volume IV – “Field Performance Assessment of Press-Brake-Formed Steel Tub Girder Superstructures”
  • Volume V – “Fatigue Performance of Uncoated and Galvanized Composite Press-Brake-Formed Tub Girders”
  • Volume VI – “Field Performance and Rating Evaluation of a Modular Press-Brake-Formed Steel Tub Girder With a Steel Sandwich Plate Deck” 

The Short Span Steel Bridge Alliance provides essential information to bridge owners and designers on the unique benefits, innovative designs, cost competitiveness, and performance related to using steel in short span installations up to 140 feet in length. SSSBA partners comprise bridge and buried soil steel structure industry leaders, including manufacturers, fabricators and representatives of related associations and government organizations.
