Abstract:The interfacial debonding detection approach for concrete-filled steel tubular (CFST) members using surface-mounted piezoelectric-lead-zirconate-titanate (PZT) actuators and sensors is experimentally and numerically investigated. In this study, an interfacial debonding detection approach using surface wave measurement with PZT patches is propoed firstly and experimental investigation on the feasibility of the proposed approach with two CFST specimens with different levels of interface debonding defects is carried out. For comparison, a PZT sensor is also embedded in concrete core to measure the stress wave traveling from the surface-mounted PZT actuator. Experiment results indicate that the voltage amplitude of the embedded PZT sensor representing the wave propagation from the steel plate into the concrete core decreases due to the existence of interfacial debonding defect, but the output signal of the surface-mounted PZT sensor increases accordingly when interface debonding occurs. Moreover, the increment of surface-mounted PZT sensor measurement is related to the dimension of the interface debonding defects. The experimental finding implies that the interface debonding is detectable using surface wave measurement. In order to investigate the mechanism of the proposed approach, numerical study on the wave propagation process in CFSTs is further discussed by using three-dimensional (3D) solid element models and two-dimensional (2D) plane strain models, respectively. Finally, in order to consider the effect of nonhomogeneous meso-scale structure of concrete on the wave propagation, a random aggregate method (RAM) is employed to model the concrete core and multi-physical fields coupling numerical analysis on stress wave propagation of the CFST member with different interface debonding defects is performed. The numerical findings meet well with the experimental observations and the results indicate that the interface debonding of CFST can be detected efficiently using surface wave measurement.

Dr. Bin Xu is currently the Minjiang Scholar Professor of Civil Engineering, a professorship appointed by Fujian Provincial Government, at Huaqiao University, Xiamen, China. He currently is the Director and Founder of the Key Laboratory for Intelligent Infrastructure and Monitoring (IIM) of Fujian Province, and the Director and Founder of the International Centre for Safety and Sustainability of Civil Engineering at Huaqiao University.
Before joining Huaqiao University, he was a Lotus Scholar Professor of Civil Engineering (a professorship appointed by Fujian Provincial Government) at Hunan University from 2005 to 2016 and was also the associate dean of the College of Civil Engineering at Hunan University from 2010 to 2016. He was also the Director of the Hunan Provincial Key Lab on Damage Prognosis for Engineering Structures from 2015 to 2016 at Hunan University. He taught and carried out research at the Lyles School of Civil Engineering at Purdue University as a Curtis Visiting Professor appointed by Purdue University in 2014-2015 academic year. He had been invited and financially support by European Commission to work at Sapienza University of Roma in 2010 and hired by University of Western Australia as a Gledden Visiting Senior Fellow from 2007 to 2008. Before starting working in China in 2005, he worked at University of Missouri-Rolla in US as a Post-Doc from 2003 to 2005 and at Ibaraki University in Japan as a Japan Society for the Promotion of Science (JSPS) postdoctoral fellow from 2001 to 2003.
He has been the supervisor of 7 Ph.D., 1 Post-Doc, 4 international visiting students and over 60 MS students. All of his PhD students are working at universities. Dr. Xu has committed to securing competitive external funds to support programs, research, and labs. He has been the PI and Co-PI of 14 competitive government funded research projects including a China- European Commission international collaborative research project, an international collaborative research project between National Natural Science Foundation of China (NSFC) and National Natural Science Foundation (NSF) of US, and a number of NSFC research projects. He is also the recipient of Grant-in-aid of 7 talent programs sponsored by China Ministry of Education (CMoE) and other government agencies.
He also serves on various academic societies as Editor-in-Chief, Executive Editor, Associate Editor, Guest Editor or editorial board member for international journals and professional committees as Standing Committee Member, Executive Member or Committee Members.
