2 STRUCTURAL USE OF GLASS an introduction for building professionals Sutton Place Hotel, Vancouver BC September 25, e.de COURSE OVERVIEW The unique physical and aesthetic properties of glass, which make it a suitable material for windows, were already well-known, highly valued and used by the Romans. Glass is an elusive material, requiring careful treatment and handling due to its brittleness, that in the past was almost always used exclusively as a structurally subordinate infi ll material largely due to prevalent uncertainty of its structural behavior. As a transparent or translucent component of the building envelope, glass serves to act as a fi lter protecting the enclosed space from surrounding conditions such as weather, temperature, sound and pollution while simultaneously acting as a source of external light from the sun. Furthermore, it defi nes space without materializing its boundaries while guarding the buildinguser s privacy and safety. The fi rst, rather intuitive, examples of the use of glass as part of the structural concept can be found in the English glass houses of the 19th century where delicate wrought iron frames were braced and held in plane by the glass. Since then, a continuously increasing demand for greater portions of transparent building envelopes has initiated thorough examination of glass and its potential as a struc- tural element. This development was further prompted by the effort to decrease the size and presence of structural sub-frames in modern architecture. Today, glass has evolved beyond simply providing light and protection from the elements. More and more, glass is often used as a multifunctional element serving structural purposes, as well as playing a key role in the thermal performance of a building. Glass has become such an integral part of highfunctioning building envelopes, it is diffi cult to imagine the existence of innovative design concepts in contemporary architecture without it. The idea of using glass, not only as a subordinate infi ll panel, but rather, intentionally to employ and exploit this material s structural, thermal and aesthetic advantages in specifi c applications, calls for an interdisciplinary design process which involves architects, as well as structural engineers and material scientists. The primary goal of this seminar is to provide building professionals from various backgrounds a broad understanding of glass design and engineering. This course presents a wide spectrum of information about glass needed to design, detail, and implement structural glass elements and façade components.

4 The at The at the Technische Universität Dresden, directed by Prof. Dr.-Ing. Bernhard Weller, covers a wide spectrum of building construction topics with a balanced approach between research and teaching. Aside from traditional aspects of building construction, the structural use of glass forms a major component of institute lectures. Research and development is conducted in close collaboration with industrial and institutional partners, thereby addressing current and future demands within the building industry. Among the primary research fi elds are applications of structural glass and energy performance of building envelopes. More specifi cally, glazing topics focus on the use and development of composite materials; the structural connection of glass elements; and the use of adhesive connections. The aesthetic and structural design of photovoltaic elements, as well as the building physics of facades, are pertinent areas of interest related to energy performance of building envelopes. Bernhard Weller Professor and Director of the Philipp Krampe Structural Engineer Bernhard Weller is a Professor of Civil Engineering and Director of the at Technische Universität Dresden. He studied civil engineering at RWTH Aachen and began his career as a research assistant at the Institute of Concrete Structures in Aachen. Previous to his appointment as Professor at the Institute of Building Construction in 1996, he worked as an engineering consultant with an emphasis on structural design. His expertise lies in the design, testing, and use of glass, and so it follows that his research interests focus on the material appropriate design of glass, as well as adhesive glass connections. In 2005 he lectured as a Visiting Professor at Columbia University in New York. Stefan Reich Structural Engineer Philipp Krampe is a research assistant at the Institute of Building Construction at. He graduated with a degree in structural engineering from the Technical University Berlin. After completing his degree he worked as a structural engineer for fi ve years at several engineering offi ces. His primary responsibilities included the structural design of buildings using various materials and systems, comprising high rise buildings, as well as project coordination while his work in Dubai for 1.5 years. At the Institue of Building Construction he is now involved in the research of glass constructions and holding lectures pertaining to facade design and structural use of glass. Gary W. Berkeley, P. Eng. Principal Berkeley Engineering Ltd British Columbia Stefan Reich is a research assistant at the Institute of Building Construction at. He graduated from TU Dresden with a degree in civil engineering; he also holds degrees in building management from the University of Northumbria, UK and in economics from the University of Hagen. He worked as an intern engineer at Thornton-Tomasetti Engineers. Afterwards he was engaged as a structural engineer at Leonhard Andrä und Partner for four years. Since joining the Institute of Building Construction his research includes the development of an innovative spatial structure with glass as compression chord within the system. In addition to research, he provides lectures in building construction. Gary Berkeley studied Civil/Structural Engineering at the University of British Columbia. After several years designing precast/prestressed concrete structures and pre-engineered metal buildings, he was introduced to the commercial glazing industry in Vancouver by a prominent local glazing contractor in Since 1991 Gary has practiced in the commercial glazing industry, specializing in high rise curtain wall and structural glazing, in BC and Washington State. He has designed many glass guards, canopies, stair treads and fi n-supported walls. Local projects include the Shangri-La Tower and the Vancouver Convention Centre. Gary chaired the Technical Committee of the Glazing Contractors Association of BC from 1995 to 1999.
