Abstract:
SP28 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 paper summarizes the finite element analysis procedure and discusses the approximations that are introduced in the analysis of thin shell structures. A wide range of different finite elements that have been developed for the analysis of thin shells are described, including both curved as well as planar types. Comparative performances of the different elements in the analysis of several example shell structures are described. Some conclusions are drawn with respect to the relative merit of the various elements.

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)
