Influence of Concrete Subsurface Voids on Elastic Structural Behavior of Moment Resisting Frame: A Preliminary Study with the Use of Concrete Ultrasonic Echo Tomography
Publication: Forensic Engineering 2022
ABSTRACT
Ultrasonic echo tomography (UET) is a non-destructive test method to obtain 3D images of concrete subsurface conditions that can be used to identify the extent and the locations of subsurface defects. In this preliminary study, UET scanning was performed on a limited number of post-tensioned (PT) beams of a concrete moment resisting frame structure. In some beams, concrete subsurface voids with a plan dimension up to about 4 m were detected underneath dense reinforcement. Destructive exploration by chipping away concrete was performed afterward to further investigate the UET test areas exhibiting signs of possible subsurface voids. It was observed during the destructive exploration that some of the detected voids could vertically extend into concrete beams by a depth of 100 mm (4 in.). The relationship between the extent of subsurface voids and the fundamental circular frequency of the frame structure was determined in this study. Based on this relationship, the maximum allowable extent of subsurface voids could be determined. Future research needs were proposed.
