Speakers

Keynote Speaker I


Prof. WONG Kwai Kwan


Research Director of CNRS (National Center of Scientific Research), France

University of Lyon/ENTPE, France

Prof. Wong Kwai Kwan is a Research Professor in Civil Engineering of the French National Center for Scientific Research (CNRS). He is leader of the research group "Sustainable Structures & Infrastructures" of the Laboratory LTDS (associated to CNRS) and a part time professor of the French National School of State Public Works (ENTPE). He has intervened in many courses including soil mechanics, tunnelling and underground works, continuum mechanics, limit equilibrium analysis, strength of materials, structural analysis, theory of plates and shells. Prior to his career in research, he was a geotechnical engineer with Simecsol (now Arcadis), involved in construction projects in France and oversea (1984-90, 1994-95). His PhD (1994) is on the thermal-mechanical behaviour of underground structures. He received his M Eng. (1984) in France and B Eng. (1981) in civil engineering in Hong Kong. He is member of a few national associations: Rock Mechanics (CFMR), Soil Mechanics (CFMS), Tunnelling and Underground Works (AFTES).
Dr Wong's current research is focused on the TCHM behaviour of geomaterials and geostructures:
• Underground storage of nuclear wastes and CO2
• Soils from relatively dry state to quasi-saturated with occluded air bubbles
• Rammed earthen constructions
• Tunnel excavation with face confinement

Keynote Speaker II

Prof. Chin Jian Leo,

University of Western Sydney, Australia

Chin Leo received his education at the University of Adelaide, University of Queensland and University of Sydney. He obtained his PhD in 1994 from the University of Sydney and is currently a Professor at the University of Western Sydney, Australia. He has professional experience working in infrastructure and geotechnical engineering projects, including soil investigation, slope stability analysis and geotechnical issues of soft soils. Early in his research career, he studied groundwater and contamination problems in soils. During this period, he developed several numerical models for contaminant migration in porous media. Since early 2000s, he has been involved in poromechanics research dealing with consolidation, sedimentation-consolidation of soft soils, tunnel closure, vibrations of piles and foundations embedded in porous media. His research contributions in this area are primarily on the theoretical or computational side of continuum mechanics, in terms of formulation of the theoretical governing equations from first principle conservation laws, and development of analytical, semi-analytical and numerical finite element solution techniques. Another area of his research, mainly in the last 5 years, deals with characterization and remediation of geomaterials, namely: EPS geofoam, red mud, high power ultrasound remediation of contaminated soils and characterization of compacted sites using unorthodox techniques, such as by microtremor measurements. In this area of research, his contributions are primarily in relation to laboratory (triaxial, true triaxial, consolidation, high power ultrasonics etc), and field experimental work, with a significant computational component. He currently leads the GWEE (Geotechnical, Water and Environmental Engineering) research group at UWS.

Keynote Speech Title: The Evolution of Architectural Membranes

Abstract: Architectural membranes are the most lightweight constructive solutions available nowadays for spaces closuring. They are mostly used to make roofs and increasingly used in facades. In its origin is one of the oldest materials used by man to build human shelters – natural animal skins - later substituted by textile fabrics using natural fibers from vegetal or animal origin. These primitive membranes are still used to build traditional human shelters, generally associated to nomad cultures, such as the Mongolian Yurt, the Tuareg Tent or the Bedouin Black Tent. During the second half of the XXth century, architectural membranes evolved, mainly driven by the development of polymer composites. With the use of fluorine based polymers they present nowadays a life span that can exceed 25 years and can be opaque or assure different degrees of translucency, but not transparency when structural properties are required. In structural membranes, a textile woven fabric is used on the membrane base structure. The most common architectural membrane is the PVC coated Polyester (PES) fabric. Nonstructural transparent architectural membranes, made of homogeneous polymer foils, are becoming more popular nowadays. If in less demanding uses PVC and PE can assure a transparent closure, in permanent structures, Ethylene Tetrafluoroethylene (ETFE) foil can guarantee more interesting properties in terms of durability and stability.

Speech Title: "Seismic Control of a Nonlinear Benchmark Building Using Particle Tuned Mass Dampers"

Abstract: In recent years, the particle tuned mass damper (PTMD) is widely studied as a new type of passive control device. But previous studies have evaluated the vibration control effect of the PTMD in view of the root mean square (RMS) ore peak value. This paper firstly introduces the concept of additional equivalent damping ratio from the perspective of energy dissipation to analyze the vibration control effect of a particle tuned mass damper, which is composed of a solid mass in a container, and is located at the top of a 9-story nonlinear benchmark building. This benchmark model is developed to provide a common basis for comparing the effectiveness of different structural control systems when applied to a realistic structure subjected to earthquake actions. In order to increase the speed of computation associated with evaluating the vibration control effect of the PTMD in the analysis process, a reduced model is developed specifically from finite element model (FEM) by GUYAN Reduction method, which has been elaborately tuned to coincide well with the FEM in terms of both modal frequencies and mode shapes, which ensures that we can use the reduced model instead of the original FEM in the analysis.
The numerical simulation shows that the PTMD can significantly increase the damping ratio of the structure by 2.91%, 2.41%, 3.44% and 3.13% when placed at the top of the primary structure subjected to El Centro, Hachinohe, Northridge and Kobe waves respectively, which makes the uncontrolled structure’s damping being double, thus reducing the displacement, velocity and acceleration response of the primary structure subjected to different seismic waves. At the same time, the vibration control effect of the PTMD system subjected to far-field waves is much larger than that subjected to near-field seismic waves. Whichever the seismic wave the primary structure is subjected to, the additional equivalent damping ratio can reach the maximum when the PTMD is placed at the top of the primary structure, thus the vibration control effect can reach the best. Consequently, the PTMD can effectively control the vibration of the first order mode for a multi-degree-of-freedom structure. The paper can provide the theoretical basis for further engineering application of particle damping technology.
