While cracks and corrosion can be detected visually, honeycomb damage cannot be detected by observation with the naked eye. In this study methods of detecting and locating honeycomb damage using three operator algorithms were compared. Honeycomb blocks were prepared and placed at predetermined locations along reinforced concrete beams with 1200x75x125n1m size. Honeycombs were located in the beam near one of the supports, in between mid span and support, at mid span, at symmetrical locations and randomly. A total of five damaged beams were prepared for the studies; with one beam prepared for the purpose of control. Modal testing method was used to detect the honeycombs. The test was done using a shaker to excite input to the beam. Eigenvalue data from the modal testing was used to detect the presence of honeycombs in the reinforced concrete beams. Eigenvector data from modal testing were used for detecting honeycomb locations. Eigenvector values were post-processed for detecting these locations. The best results were obtained using the
Geometric Mean Operator.
