Forward Time Domain Ground Penentrating Radar Modeling Of Bridge Decks For Detecting Deterioration, Kimberly Belli, Sara Wadia-Fascetti, Carey Rappaport
Forward Time Domain Ground Penentrating Radar Modeling Of Bridge Decks For Detecting Deterioration, Kimberly Belli, Sara Wadia-Fascetti, Carey Rappaport
Sara J. Wadia-Fascetti
Ground penetrating radar (GPR) for nondestructive testing is a relatively young technology, especially with application to civil infrastructure such as bridges and roadways. Conventional methods of processing and analyzing GPR data for civil infrastructure are often qualitative, using relative reflection amplitude from subsurface boundaries or reinforcing steel (rebars) as an indicator of health. This poster brings well understood electrical engineering analysis tools to the application of nondestructive testing of bridges using GPR. Using iterative forward modeling to improve upon conventional permittivity and depth calculations, a computational model geometry is computed for the assumed bridge deck with no anomalies present. A …

Sara J. Wadia-Fascetti
At the present, a large proportion of our nation's bridges and roadways are falling into disrepair. About 27.5% of U.S. bridges are structurally deficient or functionally obsolete (ASCE, 2001, 2003). Nondestructive testing methods, such as GPR, are becoming more and more important in diagnosing the condition of such concrete structures. GPR is a high-resolution electromagnetic technique used to investigate the immediate subsurface of the earth, building materials, roads, and bridges. This poster shows my work in GPR modeling during a summer undergraduate experience through CenSSIS. A specialized MATLAB toolbox designed by Kim Belli created all data presented here. The use …

Characterization Of Gpr Antenna Radiation Pattern For Implementation Into Fdtd Simulation, Bryan Lavign, Laura Carey, Kimberly Belli
Characterization Of Gpr Antenna Radiation Pattern For Implementation Into Fdtd Simulation, Bryan Lavign, Laura Carey, Kimberly Belli
Kimberly Belli
This poster is to present an experimental procedure & associated results providing insight into the directivity of a 2 GHz air-coupled GPR antenna donated by Geophysical Survey Systems, Inc. The data collected from the experiment is analyzed and implemented into a 2D FDTD code for simulation of the antenna. The output from the FDTD model with improved excitation is compared to data collected in the field using the GPR antenna.
