Increased awareness of the economic and social effects of aging, deterioration and extreme events on civil infrastructure has been accompanied by a recognition of the need for advanced structural health monitoring and damage detection technologies. Structural health monitoring (SHM) has been a fast-developing domain in engineering disciplines especially in the civil engineering field. Use of field instrumentation to validate structural designs and to characterize performance is increasingly becoming a part of civil infrastructure projects. Soil-structure interaction and the geotechnical measurements play important roles for the overall assessment of the structural health. Instrumentation and monitoring technologies have been used successfully in challenging geotechnical projects to assist in the quantification of retrofit measures, seismic risks, construction progress, in-situ loading and emergency risks.
This workshop aims to share knowledge and lesson learned from various parts of the world for research and applications of innovative technologies for instrumentation and monitoring of geotechnical engineering and civil infrastructures. Two keynote speakers will share different monitoring technologies that have been developed for civil infrastructure monitoring: Professor Shi Bin from Nanjing University will share about different developments in embedded fiber optic (FO) sensing technologies for geo-monitoring in China and Dr. Paul Sumitro from Smartsensys, LLC, USA, will present various SHM technologies including wireless MEMS-based sensors, scour detection sensors, video optical imaging and UAV (unmanned aerial vehicle) technologies for structural and geo condition monitoring.

Speech Abstract: With ultra-high resolutions, fiber optic sensing technology has significant potential for application in the Geotechnical and Geoenvironmental domains. Characterized by linearity and long length and scale, transportation engineering, in particular, can benefit from fiber optic sensors, which have several advantages over conventional monitoring technologies such as non-point monitoring, good anti-interference, good durability and stability. For the past fifteen years, several technologies have been developed including point measurement systems using Michelson and Fibry-Perot, quasi-distributed systems using Fiber Bragg Grating and fully distributed systems using OTDR, ROTDR and BOTDR/A. This presentation will give a brief history of fiber optic sensor and account for several practical applications of the sensors in actual case studies.

Speech Abstract: Structural health monitoring (SHM) is an important technology that integrates mechanics, advanced opto-acousto-electronics, mechatronics and computer applications for the purposes of ensuring physical structure stability and functionalities. This presentation will introduce several new sensing technologies for SHM including terrestrial 3D LiDAR scanners, laser Doppler vibrometer, piezo-electric skin sensor, wireless MEMS based accelerometers, GPS-based cameras and aerial photography. For large Civil system monitoring, SHM technology goes beyond sensors and may require system-level monitoring strategy design. This presentation will examples of multiple sensor integrated monitoring systems and actual application to tunnel monitoring.
