Jun Kanda / Professor / Division of Environmental Studies Department of Socio-Cultural Environmental Studies / / Structural Safety, Wind Engineering, Earthquake Engineering Career Summary 1970: Graduated, Faculty of Engineering, The University of Tokyo 1979: Ph D in Civil Engineering and Building Sciences from the University of Edinburgh 1972-80: Takenaka Corporation 1980-96: Associate Professor, The University of Tokyo 1989: Visiting Associate Professor, Johns Hopkins University 1995: Visiting Professor, Stanford University 1996-: Professor, The University of Tokyo Educational Activities Graduate School: Structural Safety, Advanced Wind Engineering, Exercises for Space Environment Formation Undergraduate: Introduction to Structural Engineering, Exercises for Building Structure Research Activities Wind tunnel studies have been conducted in order to model dynamic wind effects on various cylinder shapes. And at present a computer controlled multiple-fan driven wind tunnel has been developed. Probabilistic design earthquake ground motions have been proposed by considering scenario-based earthquakes with uncertain parameters. Optimum safety based on life cycle costs are studied with an emphasis on load modeling as well as failure cost evaluation. The A.I.J. award was received in 1996 for structural engineering research conducted on practical applications of an optimum reliability index for buildings.

Advisory member for committees in Nuclear and Industrial Safety Agency, METI Future Plan Structural safety problems should be treated as environmental issues. Information on matters related to structural safety should be provided to ordinary citizens by professional engineers in the process of sharing of decision making activities affecting infra-structure of a society. The role of engineers has to be stressed and deregulation has to be considered seriously in order to empower citizens by transferring responsibilities to them in decisions involving safety. Most of wind experiments have been conducted in a boundary layer wind tunnel by simulating stationary turbulent winds. Now a computer controlled multiple-fan wind tunnel can be used to create non-stationary winds which are responsible for numerous unsolved aerodynamic problems on bluff bodies and a further developments are expected for new types of wind tunnels. Messages to Students Environmental studies are still in the early stages of their development in their respective disciplines. Problems common to seemingly disparate fields, such as structural engineering and social sciences, are shared in our department and division. Research and education in environmental studies are open minded and inter-disciplinary endeavors, which makes them stimulating and exciting. In fact, we invite all students to form a new discipline of environmental studies.
