Publication Date 2011
Media Count 14p
Personal Author D. S. Parmar
Abstract The proposed research at the Denbigh Blvd. in the City of Newport News, Virginia was completed according to the plan of action prepared in consultation with the VDOT and the Virginia Council of Transportation Innovation and Research (VCTIR). The major elements of the work are shown below: (1) Research Preparation: review of the updated status of the bridge monitoring based on the feedback from VDOT; (2) Discussion of the Research Plan with VDOT/VCTIR; (3) Site visits for test site selection the bridge; (4) Testing of the battery operated Micro-II Digital DAQ system for experimentation at the test site; (5) Planning of the Micro-II Digital DAQ system Acoustic Emission (AE) sensors for installations on the test site; (6) AE testing, data acquisition and analysis; (7) Analysis of the AE data in a linear and 2D framework to locate the damages; (8) Establish AE bridge inspection procedure and methodology based on the studies during quiet/low and peak traffic periods; (9) Investigate the AE generation from freight trains on the bridge structure component; (10) AE data acquisition, recording and analysis on a near real time basis.
