Reinforced Concrete Structures: Analysis and Design by David Fanella pdf

Reinforced Concrete Structures

Preface by David Fanella (Author):

This book presents subject matter related to the analysis and design of reinforced concrete structural members. The focus is on the design of elements in reinforced concrete buildings where the primary reinforcement is steel reinforcing bars or steel wire reinforcement that is not prestressed. To safely and economically design reinforced concrete structures, a thorough understanding of the mechanics of reinforced concrete and the design provisions of current codes is essential. The purpose of this book is to present and explain the following in a simple and straightforward manner: (1) the underlying principles of reinforced concrete design; (2) the analysis, design, and detailing requirements in the 2008 edition of Building Code Requirements for Structural Concrete and Commentary by the American Concrete Institute (ACI) and the 2009 edition of the International Building Code by the International Code Council (ICC).

Frequent reference is made to the sections of these documents (especially those in the ACI Building Code), and it is assumed that the reader will have access to them while using this book. Information on the properties of the materials that constitute reinforced concrete and a basic understanding of the mechanics of reinforced concrete must be acquired prior to exploring code provisions. Design and detailing provisions given in the code change frequently, and it is important to have an understanding of the core elements of reinforced concrete design in order to correctly apply these provisions in practice.

Presented in Chap. 1 are a definition of reinforced concrete and a basic synopsis of the mechanics of reinforced concrete. Typical reinforced concrete members and the fundamental roles they play in buildings are discussed. The main purpose of this discussion is twofold: (1) to introduce the types of concrete elements that are covered in the chapters that follow and (2) to illustrate how all of the members in a structure are assembled. A brief overview of construction documents and the main events that occur in the construction of a cast-in-place concrete building are also covered. Again, the purpose is to make the reader aware of the important topics that are encountered in any building project.

Mechanical properties of concrete and reinforcing steel are summarized in Chap. 2. Basic information on the mechanics of concrete deterioration and failure is provided, which gives insight into the strengths and weaknesses of concrete. Also covered in this chapter are (1) methodologies for proportioning concrete mixtures, (2) durability requirements, and (3) evaluation and acceptance criteria.

General information that is applicable to the analysis and design of any reinforced concrete building is provided in Chap. 3. Included are the loads that must be considered in design and analysis methods pertinent to reinforced concrete structures. Approximate methods of analysis and moment redistribution are also covered. Chapter 4 contains the general requirements that must be satisfied for strength and serviceability. These requirements form the basis of design of all reinforced concrete members. Concepts of the strength design method of analysis are introduced, including required strength and design strength. Load factors, load combinations, and strength reduction factors are also covered, as are general provisions for deflection control. General principles and requirements of the strength design method are presented in Chap. 5. The design assumptions of this method and the basic techniques to determine nominal strength of a reinforced concrete section subjected to flexure, axial load, or a combination of both are covered in detail. A thorough understanding of the material presented in this chapter is essential before continuing on to subsequent chapters. Chapters 6 through 10 contain design and detailing requirements for the following reinforced concrete members: (1) beams and one-way slabs, (2) two-way slabs, (3) columns, (4) walls, and (5) foundations. Each chapter contains techniques on how to size the cross-section, calculate the required amount of reinforcement, and detail the reinforcement. Design procedures and flowcharts provide road maps that guide the reader through the requirements of the code. Also included are numerous design aids and comprehensive worked-out examples that facilitate and demonstrate the proper application of the design provisions. The examples follow the steps of the referenced design procedures and flowcharts and have been formulated using structural layouts that are found in typical concrete buildings.

These examples further help the reader to understand how members work together and how loads are transferred through a structure. Throughout the discussions and in the examples, the practical aspects of reinforced concrete design are stressed at length. These fundamental concepts are presented to familiarize the reader with important aspects of design (other than those that are theoretical) that need to be considered in everyday practice. Emphasis is placed on sizing concrete members on the basis of formwork considerations and detailing reinforcement so that they adequately fit within a section. The content of this book is geared to both undergraduate and graduate students, as well as to practicing engineers who need to become familiar with current code design requirements or need an update on reinforced concrete design. Engineers studying for licensing exams will also find the material presented here to be very useful.
