Scope and Objectives
Structural Health Monitoring (SHM) involves the use of various sensing devices and ancillary systems to monitor the in-situ behaviour of a structure to assess the performance of the structure and evaluate its condition. Because of well demonstrating its effectiveness in helping reduce operational costs and increase safety and reliability, it has attracted numerous researchers working in the area for the last three decades. Structural Health Monitoring (SHM) research can be divided into three main categories: (i) system development, (ii) sensors/measurement and (iii) applications. This Seminar will report the recent advances in SHM in these three categories. Under the first category, a number of test-beds have been selected covering a range of civil structural systems from laboratory models (two large-scale bridge models) and four real structures (i.e. a highway bridge, one 5-star-green rated medium-rise building, and two footbridges at QUT). In the sensors/measurement category much of the recent work has been done to enhance the Fibre Bragg Grating (FBG) sensing technology. Recent developments include new FBG strain modulation methods and new FBG accelerometers using axial and/or transverse forces and vertical displacement measurements. The application category includes number of ongoing projects on developing various Damage Detection methods to detect damages in bridges, buildings and dams. Methods to identify the effective prestress force in prestressed concrete box girder bridges by combining various Moving Load Identification (MLI) methods and Electromagnetic Ultrasonic Transducers have also been developed. Besides, the use of SHM for asset management will also be discussed. In addition, in the next edition of the Australian Bridge Design Codes, AS5100, there will be a section on SHM. To include a section on SHM in a design standard is a breakthrough in western countries. The concept of this SHM standard for bridge design will also be included in the Seminar.
Prof Tommy Chan is a Full Professor of Civil Engineering in the School of Civil Engineering and Built Environment at Queensland University of Technology (QUT). He is also the Founding Chair and President of the Australian Network of Structural Health Monitoring (ANSHM). Prof Chan has been actively involved in carrying out research on Structural Health Monitoring (SHM). He has published over 280 technical articles and over 20 years of experience in Structural Health Monitoring (SHM) of various significant long span bridges in Hong Kong and the Mainland China. His research and consultancy work on the four cable supported bridges in Hong Kong could be dated back as early as since their construction while he worked as an academic in The Hong Kong Polytechnic University. His papers are frequently cited by the peers, leading to over 3600 citations and an h-index of 33. He is also a professional engineer and Fellow of the Hong Kong Institute of Engineers. Besides SHM, his research interests include bridge engineering, structural dynamics, Moving Force Identification, optical fiber sensors and Weigh-in-Motion Studies.
