He has served as head of FPL Physical and Mechanical Testing Unit overseeing mechanical testing programs for wood-based materials and structural components. Currently, his research focuses on the development and use of nondestructive evaluation technologies for various wood products and structures. Dr. Ross has worked on various NDE related projects including the in-place assessment of members on the USS Constitution. He has written or co-authored over 100 technical reports/articles about nondestructive testing, and jointly holds 12 patents in the nondestructive testing area.

Brian K. Brashaw
He is a Director of the Wood Materials and Engineering Program with the University of Minnesota Duluth, Natural Resources Research Institute. He is a Project Leader of the NDE research efforts at the Natural Resources Research Institute and is a coordinator of the NRRI Physical and Mechanical Testing Laboratory. He has developed and conducted projects with wood materials emphasizing applied product development and technology transfer.

Mr. Brashaw also has performed nondestructive evaluation and destructive testing of composite materials and structural components for building code approval, and analyzed experimental results. His current NDE research focus areas include: NDE technology assessment and implementation for logs, lumber, panel and end products; development of hardwood structural products (l-joists and trusses and performance testing); participation in ASTM D-7 Wood standards development for NDE of wood products; and technical assistance for all wood products manufacturing.

Xiping Wang, PH.D.
He is a research scientist of the Structural Condition Assessment and Rehabilitation Research Unit at USDA Forest Products Laboratory, Madison, Wisconsin and a research associate of the NDE research efforts at the University of Minnesota Duluth Natural Resources Research Institute. His research activities focus on nondestructive evaluation of wood and wood-based materials, NDE of wood structural members/systems. He has worked on various structure inspection projects including in-place assessment of the key structural members on the National Historic Landmark C.A. Thayer. He is the author and co-author of more than 40 refereed scientific articles and is a reviewer of manuscripts for publication in several peer reviewed journals

Course Description

This seminar is an intensive overview of material evaluation practices and procedures used for assessing the structural condition of existing structures and covers as many aspects of evaluating structures as possible. State-of-the-art information on visual inspections, destructive and nondestructive testing (NDT), and the hands-on experience provided in this seminar, are essential for those involved in evaluating concrete, masonry, wood, and metal structures.

After a brief review of structural condition assessment procedures and guidelines, the seminar will cover condition surveys, planning a materials evaluation, destructive and nondestructive testing, limitations of NDT testing, statistical evaluation of test data, and interpretation and use of test results. Nondestructive testing techniques for establishing in-place material properties for concrete, masonry, wood, and metals are a primary focus.

The hands-on workshop and case studies will enhance understanding of condition survey and inspection procedures, and destructive and nondestructive testing techniques.
