Abstract:结构非线性行为识别是结构灾后损伤评估的关键。扩展卡尔曼滤波(Extended Kalman Filter,EKF)有助于解决结构动力响应测量不完备的问题,但一般要求结构质量已知。针对仅部分加速度响应已知和结构质量未知情况下结构非线性恢复力的识别问题,提出一种结合EKF和最小二乘算法的结构非线性恢复力及质量识别的迭代算法。该方法基于质量估计值和部分自由度上的加速度响应测量,通过EKF预测完整响应时程,再利用最小二乘法识别修正质量分布,循环迭代至收敛,最后基于质量收敛值实现物理参数(刚度、阻尼、非线性)的识别,进而得到非线性恢复力。以一个含Bouc-Wen磁流变阻尼器的多自由度体系的数值模型为例,考虑4种不同的质量初始误差,通过数值模拟验证该方法识别结构质量及非线性恢复力的有效性。同时考虑加速度测量噪声的影响,证明了该方法的鲁棒性。

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.
