    Modern pressure measurement technology and structural design for wind: a new collaborative paradigm for wind and structural engineers

    Get PDF
    Against a brief historical overview, this paper presents the Database-assisted Design (DAD) approach, a conceptually simple, transparent, and rigorous approach to structural design for wind, which fully exploits the potential of modern computational capabilities and pressure measurement technology. A novel collaborative framework between wind and structural engineers assures the effectiveness of this approach and establishes clear lines of responsibility for their respective contributions to the design process. Wind effects with design mean recurrence intervals are determined by DAD more accurately than is possible by using conventional methods for estimating aerodynamic loads, dynamic effects, and wind directionality effects. The DAD approach is consistent with Building Information Modeling (BIM) requirements, and is in principle applicable to most structures for which wind pressures are determined by aerodynamic testing or CFD methods

    Conference on Extreme-value Theory and Applications

    It appears that we live in an age of disasters: the mighty Missis­ sippi and Missouri flood millions of acres, earthquakes hit Tokyo and California, airplanes crash due to mechanical failure and the seemingly ever increasing wind speeds make the storms more and more frightening. While all these may seem to be unexpected phenomena to the man on the street, they are actually happening according to well defined rules of science known as extreme value theory. We know that records must be broken in the future, so if a flood design is based on the worst case of the past then we are not really prepared against floods. Materials will fail due to fatigue, so if the body of an aircraft looks fine to the naked eye, it might still suddenly fail if the aircraft has been in operation over an extended period of time. Our theory has by now penetrated the so­ cial sciences, the medical profession, economics and even astronomy. We believe that our field has come of age. In or~er to fully utilize the great progress in the theory of extremes and its ever increasing acceptance in practice, an international conference was organized in which equal weight was given to theory and practice. This book is Volume I of the Proceedings of this conference. In selecting the papers for Volume lour guide was to have authoritative works with a large variety of coverage of both theory and practice
