Speaker Prof. Hong-Hu ZHU Associate Professor, Engineering Geology and Geotechnics Nanjing University, China Associate Director Suzhou Key Laboratory of Distributed Sensing & Monitoring Technology of Civil Infrastructures Abstract Since the invention of the first fiber optic sensor (FOS) in the late 1970s, various quasi- and fully-distributed monitoring technologies have emerged to date. Compared with conventional sensors, distributed FOSs have some inherent advantages such as immunity to electromagnetic interference, insensitivity to corrosion, high precision and tiny size. Recently, these sensors have been adopted to monitor strains or displacements of a variety of geotechnical structures, such as foundations, slopes, tunnels, and dams. These pilot case studies have greatly extended the real-world applications of these sensors, and have preliminarily verified their capability in ...

Speaker Prof. Ben YOUNG Deputy Head and Professor Department of Civil Engineering University of Hong Kong Abstract This paper presents the experimental investigation of cold-formed high strength carbon steel tubular stub columns and beams. The nominal 0.2% proof stress of the specimens ranged from 700 to 1100 MPa. The experimental program focuses on the square hollow sections (SHS), rectangular hollow sections (RHS) and circular hollow sections (CHS). The material properties were first measured through tensile coupon tests. A new stress-strain model for high strength steel materials is proposed. The residual stress distributions were also presented for SHS and CHS. The compressive behaviour at cross-section level was studied through testing 25 stub columns. The test results including modulus of elasticity, 0.2% ...
