Dr. Sougata Roy’s specialization is in structural engineering with expertise in: fatigue and fracture of steel bridges and structures; experimental and computational simulation of steel bridges; forensics, material investigation and field evaluation of structures; advanced computerized structural analysis; bridge design practice; and bridge specifications.

His research interests include: development of fatigue resistant connections; development and assessment of advanced structural systems; improving durability under in-service conditions and renewal of damaged and deteriorated systems; evaluating influence of design procedures, material properties, fabrication processes, and loading and environment on long-term performance of structural systems; application of fracture and damage mechanics for life prediction and critical instability; assessing system performance by large-scale numerical and experimental simulations; and infrastructure monitoring.

Dr. Roy has more than 17 years’ experience in experimental and analytical research in the academia and industry, and another 11 years’ experience in conducting and managing large bridge design projects in the consulting industry. He has also supervised doctoral and master’s students, mentored undergraduate students, and taught graduate and undergraduate courses. Sougata received baccalaureate degree in civil engineering from the University of Calcutta, India, and master’s and doctoral degrees in civil engineering from Lehigh University.

As a principal investigator, Roy has led multiple large externally funded multi-year research projects and grants in the area of steel bridge and highway infrastructure that were funded by FHWA, NJDOT, MTA New York City, PennDOT, MnDOT, Caltrans, and other government, semi-government and private industries.

He has successfully conducted experimental and computational research that has led to the development of fatigue design provisions for the AASHTO Specifications for Structural Supports for Highway Signs, Luminaires and Traffic Signal Structures. He has also contributed to the development of the AASHTO LRFD Specifications for the subject structures. Led research and assisted with the revisions to AASHTO Specifications for modular bridge expansion joints. He also contributed to the development of the AASHTO Specifications for Ultrasonic Impact Treatment (UIT). Dr. Roy has also led the effort on developing the fatigue design provisions for the ASCE Athletic Field Lighting Structures Standards, and contributed to AWS specifications for tubular structures. Dr. Roy is a recognized expert in design of orthotropic bridge decks. He has led/leading multiple research projects addressing design, and fabrication issues and developing manufacturable fatigue resistant steel orthotropic bridge decks.

Roy is the current chair of TRB Standing Committee AFH70: Fabrication and Inspection of Metal Structures and vice chair of AASHTO/NSBA Steel Bridge Collaboration TG 16:Orthotropic Deck Panels. He is also members of AISC TC 6: Connection Design and TC10: Materials, AISI Bridge Task Force, AWS TG7: Tubulars, and AREMA Committee 15: Steel Structures. He is a member and the past chair of the ASCE/SEI Committee on Fatigue and Fracture, and has served as an Associate Editor of the ASCE Journal of Bridge Engineering. He also regularly contributes to the activities of AASHTO Committee on Bridges and Structures, Technical Committee T2, T12, T14 and T17.

Dr. Roy has disseminated his research through reports for NCHRP, FHWA and other government, semi-government and private funding agencies, journal publications, conference proceedings, and special publications, and numerous presentations (including keynote addresses) at national and international conferences and committee meetings. He has co-authored Chapter 19 Fatigue and Fracture in the Bridge Engineering Handbook, Chapter 2 Fatigue and Durability of Steel Bridges in Frontier Technologies for Infrastructure Engineering, Knowledgebase for Weld Details in Steel Orthotropic Bridge Decks for AASHTO/NSBA Steel Bridge Collaboration Task Group 16, and is developing AISC Design Guide for Fatigue Design of Welded Connections using Local Stresses. He has regularly offered a short course on Fatigue and Fracture Design of Structures for PennDOT.
