This Book explains principles of designing of Silos and their construction techniques. This Book is basically limited to Concrete and steel Silos, though the approach and principles in general are applicable for other Silos also. Very few books were available on Silos. Books by Manning, Ketchum and, Faber and Mead were useful for their pressures calculations and structural design. International Codes of Practice on silo Design, like DIN (1964) and ACI (1977) were introduced subsequently. But they were satisfactory when silo sizes were small; about 12m dia. maximum. These were based on semi-empirical approaches for pressures calculation. Due to this limitation, structural and functional failures of Silos happened sporadically. During 1985, Safarian and Haris published their excellent voluminous treatise on Silos design and construction. Their book includes provisions of International codes of Practice at that time from Germany, USA, France, Soviet Union and suggestions from many international practicing Design Engineers. Subsequently, some of the International codes were revised based on the latest findings of research and practical observation results. With the introduction of the Euro Code on Silos, other Codes were revised. This book gives recommendations of these codes; viz. DIN, Euro and others codes & highlights the limitations of these codes. The main uncertain issue had been the computation of material pressures on silo walls and their bottom structures. Starting with historical developments of Silos since 1770s, this Book covers up to their causes of failures and the remedial measures. Silo strengthening measures are also mentioned. Worked out examples of material pressures computations as per the current Codes of practice are included to help proper understanding of the principles of calculation of pressures and structural design. It is expected that this Book would be very useful as a guide to young Engineers interested in the design of Silos structures and will serve as a reference to Practicing Engineers. Many practical suggestions are included on both design and construction aspects of the Silos. This would also be of immense help as course material for 'Special Structures' being conducted in educational institutes.

This book describes the critical aspects to be considered while designing different process structures and Equipment foundations of dry process Cement Plants. These comprise tall and heavy process structures, material storage structures and foundations for heavy equipment. All these are subjected to heavy and dynamic loads due to the diverse equipment they support. As the Plant sizes have been increasing, Plant loads have become very large and critical, and these are to be safely carried by the respective supporting structures and foundations. Parameters that were not critical and ignored or not accounted for earlier when Cement plant sizes were more miniature have become essential to be correctly considered in the structural designs. The methods of analysis and structural design have become more sophisticated and involved. Worked out examples of Heavy Equipment foundations are included. This book highlights common design errors likely in steel structures and suggestions for ensuring safe Engineering of the respective structures of the Cement Plants. Execution of the structures is briefly covered & Development of the Structural Design, Engineering of the structures for their safety is Included. It is hoped that this book will help young engineers, understand the types of structures and equipment foundations & their respective critical features to be considered in their supporting structural designs. This book will also serve the experienced Engineers and Plant Managers as a guide for the design and proper plant operation & maintenance. This book is first of its kind & is expected to fill the knowledge gap in designing cement plant structures
