The 17 papers in this symposium volume are intended to aid the architect, engineer, and contractor in achieving that high level of competence and interdisciplinary collaboration which, due to the inherent intricacy of shell construction, is.essentiaI. Some specific papers cover: cylindrical shells and folded plates; hyperbolic paraboloids; cable-supported concrete shells; specialized computer programs; conceptual design and construction; historical view of shell construction; outstanding recently completed examples; and problems of analysis and design.
The history of the development of shells in the United States is reviewed. Current trends and practices are examined. Observations and recommendations are made with respect to the future.
The state of the art of the analysis of hyperbolic parabolid shells is discussed.
It is the purpose of this paper to present a "state of the art" discussion of the analysis of cylindrical shells and folded plates. Because these shell systems have been used widely during the past 30-40 years in reinforced concrete structures of all types, the literature on their analysis is very extensive.
The common shallow umbrella, made of four pieces of hyberbolic paraboloid with their Z axes in a vertical position, has proven to be a handy and economical solution for covering large industrial areas, where substantial reuse of wooden formwork can easily be achieved. (Fig 7-1)
