Title: Principles Of Concrete Shell Dome Design
Author(s): Eric C. Molke and J. E. Kalinka
Publication: Journal Proceedings
Appears on pages(s): 649-708
Abstract:‘A review of the’ assumptions for the ordinary beam thebry is given, and it ‘is found that it is far from correct to treat hiqh diaphraqm (wall-like) beams as well as thin shell; in general wi th the law of the straight line distribution of stresses. Airy’s stress function method is recommended for the calculation of such structures. Dome and shell dome are defined. It is shown that a series of simply shaped shell domes with proper stiffening members can be used to build strong, light and economical structures. Ex amples are cited of the construction of Z-D shell domes in America. The theory of shell structures is presented in such a way that the reader who is not interested in mathematicaldetails is able to picture the stress distribution over the membrane. It is found that shell cupolas supported at a few points only, show stress distribution similar to the ones observed on diaphragm beams. The calculation of shell domes is carried out with the stress function method and the stress distribution is shown by trajectories in isometric views. Twenty-six references are listed.
