Abstract:

Reliable and quantitative nondestructive evaluation (NDE) methods for construction materials of wood, concrete, masonry and structural steel are needed. NSF program director John Scalzi describes some of the project areas currently being supported in the agency's $million annual research program. These include such areas as detection and warning of imminent and actual bridge collapse, structure safety monitoring systems, investigation of the vehicle-superstructure interaction on highway bridges, and computer-based measurement of 3-D displacements and strains in structures. The use of transient stress waves to detect flaws in prismatic concrete structures, pavement management using video imaging, intelligent systems for in-situ evaluation of materials and structures, nondestructive evaluation of masonry structures, strength assessment of wood-based structures are some other projects supported by the NSF.
