Excerpt from The Design of Walls, Bins, and Grain Elevators The aim in writing this book has been to present a systematic analysis of the stresses due to granular materials together with a dis cassion of the principles of design and the details of structures which contain the granular materials. Since a thorough knowledge of the theory of the retaining wall is essential to a correct understanding of the theory of pressures in bins, the design of retaining walls is taken Up first. The design of bins for coal, ore, etc., is then taken up in detail, and is followed by the design of grain bins and elevators. The sequence of the different subjects is the same as the order in which the work was developed by the author, and it is thought to be logical and consistent. While algebraic methods for calculating stresses have been given due consideration, attention is called to the graphic methods for calculating the pressures on retaining walls, and in hopper bins. Reinforced concrete is now very extensively used in the construe tion of retaining walls, bins, and grain elevators, and it has therefore appeared advisable to give a discussion of the theory of reinforced con crete and to develop the formulas necessary for use in design.
