This paper summarizes the mathematical formulation, the numerical method of solution, and the design features of a program (ELAS) for the in-core solution of linear equilibrium problems of structural mechanics.

This paper describes the general input and output requirements of a propritary computer program called EASE.*

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.
General considerations of design and use of materials are discussed. A report is given on methods of analysis, and also on wind pressures and flutter.
The state of the art of the analysis of hyperbolic parabolid shells is discussed.

The four essential problems facing a designer of concrete thin shells of revolution, more or less in order of importance, are construction, experiementation, analysis, and appearance.
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 paper presents a state-of-the-art survey of the evolution of the philosophy of design for concrete thin shell structure.

This paper describes the engineering features of a 260 ft inverted dome supported on only 8 columns around a circle (Fig 9-1). The unusual aesthetic requirements of this Garden State Arts Center 5,000 seat amphitheater demand a special structural layout quite different from the ordinary.

The design and construction of the shell roof of the Saint Mary's Cathedral in Sann Francisco is described. The roof consists of eight hyerpbolic paraboloid shells approximately 50 ft wide and 130 ft high, enclosing the prinicpal space which is some 190 ft high and 205 ft square in plan. The shell roof was built using shotcrete deposited on precast concrete ribbed forms, a system of construction devised for the project by Pier Luigi Nervi. Extensive model testing and computer analyses were performed in the course of design.
