BACKGROUND

Dr. Dr. Nims is a registered professional engineer who worked for 12 years as a consultant before entering academia. He has a wide range of interests that centers on the testing of structures. His background is in structural mechanics with emphasis in testing, bridge engineering and earthquake engineering. He has tested marine, land-based and space structures. He has over forty years’ experience as a test engineer. He has been involved in the assessment and evaluation of structures, particularly bridges and sign support structures, the mitigation of weather hazards, the isolation and reduction of motion including bridge bearings with elastomeric elements, the design of large specialty bearings and test fixtures, the use of instrumented bridge bearings to assess bridge condition, the application of passive damping to structures (friction, shape memory and viscoelastic), the analysis and design of earthquake resistant structures and the seismic behavior of secondary systems.

He enjoys teaching in the area of structural mechanics and be involved with students. He has won several teaching awards including the College of Engineering Outstanding Faculty Member Award and the Ohio Society of Professional Engineers Outstanding Engineering Educator Award. He was a mentor for the team that finished second nationally in the Prestressed/Postensioned Concrete Institute Big Beam Contest. He is the founding and current advisor for the Structural Engineers of Ohio University of Toledo Student Chapter. He has received several awards for his engagement with students including the College of Engineering Undergraduate Mentor Award and induction into Phi Kappa Phi and Tau Beta Pi. 

EDUCATION

Ph.D. - University of California at Berkeley Department of Civil Engineering, Structural Engineering, Mechanics and Materials.
M.B.A. with Distinction - University of Michigan, Ann Arbor Business School, Concentrations in finance and business economics.
M.S. - The Ohio State University. Department of Civil Engineering.
B.S.C.E. - The Ohio State University, Department of Civil Engineering. 

Dr. Nims’ active research projects August 2016:

bulletTilt Measurement and Monitoring of Jeremiah Morrow Bridge: Application of tilt meters in a real time monitoring system to large cast in-place segmental concrete bridge assess the behavior and prestressing of the bridge to account fo.

bulletAluminum Truss Overhead Sign Support Flange Damage Assessment: A forensic investigation into the corrosion d fatigue that lead to large cracks in the joints of overhead sign support structures.

bulletPreliminary Measurement and Analysis of Flexure and Shear Strain for a Carbon Fiber-Wrapped Pier Cap: Testing to evaluate the efficacy of carbon fiber wraps to strength bridge piers caps.

bulletAssessment of the Load Rating of Bridges with RF > 1.35 to Meet Special Hauling Vehicle Requirements: Short heavy trucks can overload short span bridges. This is a statistical study to assess if bridges with a rating factor > 1.35 for Ohio Legal Loads are adequate for the short heavy trucks.

bulletMagnetic Inspection of Prestressed Spandrel Beams in East Parking Garage at the University of Toledo: Post failure examination of the corrosion of prestressing in spandrel beams of a parking garage.

bulletLong Term Maintenance of the Anthony Wayne Suspension Bridge Main Cables: Study of corrosion and corrosion monitoring in the cables of a suspension bridge.

bulletVeteran's Glass Skyway Ice Hazard Mitigation: Ice falling from this large cable stayed bridge poses a hazard to travelers. Reducing the risk by assisting bridge operators is being studied.

bulletReliability of Overhead Sign Support Structures: Based on an earlier study of the inspection of overhead sign support structures the reliability is being examined. The goal is to lay the foundation for reliability based inspection intervals.

bulletComparative study of the creep behavior of prestressed concrete: a comparison of creep models.

bulletExamination of the behavior of a large post-tensioned cable stayed bridge: A large cable stayed bridge was monitored throughout its construction. The measured strain is being compared to that predicted by the contractor.
