About this book

This book offers a new calculation procedure of the structural behavior of grouped layout of silos, easy to use and with satisfactory responses.

Groups of reinforced concrete silos are structures commonly used in the food industry, where it is usually necessary to separate the storage of different types and sources of grain.

The grouped layout of silos has numerous benefits when compared with single-cell silos in which the emphasis is on creating further space for silage, normally referred to as interstice – a space formed between the edges of the group’s cells. This economic benefit, on the other hand, raises a structural problem for the designer of this type of building, which is to assess the magnitude of bending moments and hoop forces due to the structural continuity of the walls in the interstice region of the cells. Bending moments assume extreme values exactly when the interstice is loaded and the other cells in the group are empty.

To develop the formulation of the proposed analysis models, a parametric study was carried out that allowed the adequate consideration of the variables involved.

The idea is to help professionals, engineers, industrials and academics involved in this advanced interdisciplinary field as a comprehensive guide for courses offered at different levels of learning (undergraduate and postgraduate).

Table of Contents

Frontmatter
Chapter 1. Characterization and Brief Literature Review
Abstract
The problem to be solved is the calculation of stresses resultants on the walls of groups of reinforced concrete silos due to interstice loading.
Fernando A. N. Silva, Bernardo Horowitz, João M. P. Q. Delgado, António C. Azevedo
Chapter 2. Geometry and Loading
Abstract
The geometry of the silo groups of interest is shown in Fig. 2.1. They may have a thick slab (or conical hoppers with ring beams) at the bottom, and a slab, possibly on beams, at the top. Due to the thick slab close to the foundation, we will assume the cylindrical shell clamped at the bottom slab.

Chapter 3. Two-Dimensional Linear Elastic Analyses—Slice Method
Abstract
The initial procedure used in the structural analysis of reinforced concrete silo groups is to remove a horizontal slice of unit height from the group of cells, as shown in perspective in Fig. 3.1, and study it for the various expected loading cases.
Fernando A. N. Silva, Bernardo Horowitz, João M. P. Q. Delgado, António C. Azevedo
Chapter 4. Three-Dimensional Analysis
Abstract
The study of reinforced concrete silo groups using the three-dimensional finite element analysis demands from the designer hard work to formulate of the problem. Aspects such as the characterization of the geometry, the determination of the loads and choice of the appropriate boundary conditions, as well as in the interpretation of the obtained results, are examples such difficulties. Despite these difficulties, three-dimensional analysis is an important tool for understanding the structural behaviour of this type of construction.

Chapter 5. Structural Behaviour and Simplified Model Proposition
Abstract
The understanding of the load-bearing mechanism in the silo group analysed in this research, due to the loading acting in the interstice, can be intuitively understood observing the three figures presented below.
Fernando A. N. Silva, Bernardo Horowitz, João M. P. Q. Delgado, António C. Azevedo
Chapter 6. Conclusions and Recommendations
Abstract
Taking into account the analyses performed throughout the research it is possible to draw the following conclusions.
