Project by Type
BRIDGES
A major emphasis of the Infrastructure Technology Institute's (ITI) research program is nondestructive evaluation (NDE) of bridge serviceability. We are currently active in work focused on six general areas: Remote Monitoring, Fatigue Crack Evaluation in Steel Structures, Structural Stability Evaluation, Lift Bridge Diagnostics, Deep Foundation Evaluation, Measurement of Abutment Deformation, and Retrofit Evaluation. Since its inception, the Institute has been supporting research at Northwestern in co-operation with public and private sector technology deployment partners throughout the United States to address significant challenges identified by the infrastructure community. Please email David Prine, Chief Engineer at the Infrastructure Technology Institute (ITI) for further information.

CONSTRUCTION VIBRATION
These projects focus on the deployment of the combination
of several new instruments and technologies to assess and communicate
effects of construction vibrations on adjacent structures. Newly developed
instruments monitor micro-inch response of cracks to weather (long term)
and vibration (dynamic) events. Field computers are autonomously polled
to consolidate data on a central server. Centralized data are then autonomously
aggregated, synthesized, and displayed graphically over the internet
for interpretation by both engineers and the general public. Details
are available at http://www.iti.northwestern.edu/acm.
Please email Charles Dowding,
Research Professor at ITI for additional information.

ROADS
These projects involve demonstration of remote monitoring of slope and embankment failures as well as unusual subsidence with Time Domain Reflectometry (TDR) instrumentation. TDR instruments involve pulsing voltage signals down buried coaxial cables and interpreting the reflections like radar in cable. The inherent digital nature of this technology and its ability to sense both deformation and piezometric information are ideal attributes for remote monitoring. Many of these projects also involve the combination of TDR and tiltmeter instruments with autonomous monitoring. Details are available at http://www.iti.northwestern.edu/tdr/.
