Abstract:Interface debonding detection approaches based on stress wave measurement for concrete-filled steel tube (CFST) members have received a great deal of attention in civil and infrastructural engineering societies. The development of efficient computing approaches to investigate the mechanisms of the interface debonding detection approaches and the effect of interface debonding on wave propagation within CFST members is critical. In this study, the wave propagation within the cross section of CFST members with and without interface debonding under a single point excitation force is simulated with a two-dimensional (2D) spectral element method (SEM) at first and that of CFST models coupled with a surface-mounted piezoelectric lead zirconate titanate (PZT) actuator and an embedded PZT sensor in the concrete core under continuous and sweep sinusoidal signals is simulated with the 2D SEM and a piezoelectric spectral element. The debonding defect is modeled by removing concrete elements between the steel tube and the concrete core. Results show that interface debonding affects the wave propagation process, the output potentials of the embedded PZT sensors as well as the displacement responses at different locations of CFST specimens obviously. Rayleigh damping identified from experiments is introduced to the SEM models to reflect wave attenuation in the coupled models. The effect of interface debonding on the amplitude, the Fourier spectra and the wavelet packet energy of stress waves are analyzed. For comparison, another numerical model in which the PZT actuator is not located near the interface debonding defect is studied numerically and the effect of the debonding defect on the response of the embedded PZT sensor is illustrated. SEM provides an efficient way to simulate stress wave propagation and to understand the mechanisms of interfacial debonding defect detection for CFSTs with PZT technique.

Profile

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.
