The writing of this Design of Reinforced Masonry Structures Second Edition by Narendra Taly book was motivated by a professional need to update changes in the reinforced masonry design philosophy that have occurred as a result of incorporation of strength design philosophy in the 2008

Building Code Requirements for Masonry Structures reported by the Masonry Standards Joint Committee (referred to in this Design of Reinforced Masonry Structures Second Edition by Narendra Taly book as the MSJC-08 Code) and corresponding requirements of the 2009 International Building Code (2009 IBC), and to update changes brought out by the ASCE/SEI 7-05 Standard,

Minimum Design Loads for Buildings and Other Structures (referred to in this Design of Reinforced Masonry Structures Second Edition by Narendra Taly book as ASCE 7-05 Standard). While the fundamental principles of designing reinforced masonry structures discussed in the first edition

(2001) of this Design of Reinforced Masonry Structures Second Edition by Narendra Taly book remain valid, revisions in codes, specifications, and reference standards applicable to design and construction of masonry structures that have since occurred required updating that Design of Reinforced Masonry Structures Second Edition by Narendra Taly book in the form of this second edition.

The allowable stress design (ASD) method of designing reinforced masonry structures presented in the first edition of this Design of Reinforced Masonry Structures Second Edition by Narendra Taly book is still acceptable, and is expected to remain so for the foreseeable future.

However, the general trend in the structural engineering profession is to move toward using the strength design philosophy for the design of concrete structures, and load and resistance factor design (LRFD) for the design of steel structures.

Readers of the first edition of this Design of Reinforced Masonry Structures Second Edition by Narendra Taly book will note that the topic of strength design of reinforced masonry was briefly covered in App. D.

This second edition is a natural, follow-up publication that focuses exclusively on strength design philosophy for reinforced masonry structures. In addition, a new chapter on anchorage to masonry (Chap. 10) has been introduced.

Consistent with the first edition, this edition of the Design of Reinforced Masonry Structures Second Edition by Narendra Taly book is written in a stand-alone format and independent of the ASD philosophy.

While knowledge of and familiarity with the strength design principles for design of reinforced concrete structures would enable readers to quickly grasp the fundamentals of strength design of reinforced

masonry, neither that knowledge nor that of allowable stress design of masonry are considered prerequisites for understanding the discussion presented herein.

Each chapter of the Design of Reinforced Masonry Structures Second Edition by Narendra Taly book presents the theory based on first principles and is supported by references and followed by numerous examples that illustrate its application.

Like the first edition of this Design of Reinforced Masonry Structures Second Edition by Narendra Taly book, this edition is written for use by students and professionals of reinforced masonry design and construction.

It is written in a simple, practical, and logical manner, and is styled to suit as a text for teaching reinforced masonry design and construction in a classroom environment at senior/graduate level.

Frequent references to the MSJC-08 Code and ASCE/SEI 7-05 Standard are made throughout all discussions and examples in this Design of Reinforced Masonry Structures Second Edition by Narendra Taly book to acquaint readers with the design and specification requirements that must be followed; readers will find it helpful to keep copies of these two references handy while reading this Design of Reinforced Masonry Structures Second Edition by Narendra Taly book.

Chapter 1 introduces the topic of masonry design and construction—from ancient times to modern times—a practice that began as the art of construction and evolved into the modern engineered construction.

Also presented in the chapter are brief discussions of the governing building codes and specifications for masonry structures, and governing provisions of ASCE/SEI 7-05 Standard that form the basis of load calculations for analysis and design.

Masonry structures are built from units that are fabricated in production plants from clay and concrete, and hand-laid by skilled masons, one unit at a time.

Chapter 2 is devoted to a detailed discussion of both clay and concrete units with respect to industry standards, product availability, modular sizes, design properties, and applicable ASTM Standards.

Chapter 3 presents a discussion on materials of masonry construction: masonry units, mortar, grout, and steel reinforcing bars.

Reinforced masonry structures are built from placing masonry units with mortar between them, placing horizontal and vertical reinforcements, and grouting the cells of masonry units to accomplish the desired design objectives.

Adherence to the specifications of these materials is the key to acceptable performance of as-built structures, hence the importance of this chapter.

Chapters 4 through 10 present analysis and design of masonry structures subjected to flexure, shear, compression, and combined axial compression and flexure; walls subjected to out-of-plane loads;

shear walls (walls subjected to in-plane loads); retaining walls; and anchorage to masonry. Chapter 4 presents an exhaustive discussion of fundamentals of strength design philosophy and their application to flexural analysis and design of masonry structures.

This is the longest and also the most important chapter in the Design of Reinforced Masonry Structures Second Edition by Narendra Taly book for it embodies principles of strain compatibility and ductility, and requirements of the MSJC-08 Code pertaining to design for flexure, shear, deflection, and cracking moment, concepts which are used in later chapters of the Design of Reinforced Masonry Structures Second Edition by Narendra Taly book.

The author has provided in-depth explanation of fundamental principles of strength design in this chapter, followed by numerous examples designed to satisfy the many “what if” questions and curiosities of readers, particularly students.

The purpose of this chapter is to encourage discussion and to develop confidence in understanding the ramifications of improper designs.

Chapter 5 is devoted to design of compression members—reinforced masonry columns— loaded axially or in combination with bending.

Many examples are presented to illustrate the design concepts and alternatives. An in-depth discussion of interaction diagrams for columns subjected to combined axial load and bending, including detailed, step-by-step calculations for developing such diagrams, forms the highlight of this chapter.

Chapter 6 presents analysis and design of reinforced masonry walls subjected to out-ofplane loads due to wind or earthquakes.

The chapter presents a discussion and calculation of these forces based on ASCE/SEI 7-05 Standard. Also presented in this chapter are many different types of masonry walls and their uses.

Chapter 7 deals with an all-important topic of analysis and design of reinforced masonry shear walls which are used as systems for resisting lateral forces in building structures— either as the main wind force–resisting systems (MWFRS) or as the seismic force–resisting systems (SFRS).

Because of the extreme importance of this topic, this chapter provides an in-depth discussion of seismic load provisions of ASCE 7-05 Standard and design requirements pertaining to the many different types of shear walls as classified and permitted by the standard for use as lateral force–resisting systems.

Chapter 8 describes analysis and design of reinforced masonry earth-retaining walls and basement walls which are commonly used in practice.

Chapter 9 provides a discussion of masonry construction practices, with an emphasis on grouting practices. Masonry construction involves hand placement of brick or concrete masonry units interfaced with mortar, and then providing reinforcing bars as specified and followed by grouting.

Following recommended procedures for all of these facets of construction is important to ensure intended performance of the as-built masonry structures.

Connection between masonry and other structural components, such as ledger beams or other load-carrying elements that are required to transfer forces through connections, is accomplished by anchorage. Chapter 10 is devoted to analysis and design of anchorage to masonry.

The discussion in this chapter presents the various limit states that govern design of bolted connections to masonry.

The examples in each chapter are presented in a comprehensive, step-by-step manner that is easy to understand. Every step is worked out from first principles.

Typical problems are provided at the ends of Chaps. 4 to 8 and 10 for readers’ practice to develop confidence in understanding the subject matter.

The appendix provides many helpful tables that make analysis and design of masonry quick, efficient, and interesting, thus avoiding the drudgery of longhand calculations.

Use of these tables is explained in the many examples presented in this Design of Reinforced Masonry Structures Second Edition by Narendra Taly book. As with any professional book, readers will find many new terms introduced.A glossary of terms used in this Design of Reinforced Masonry Structures Second Edition by Narendra Taly book is provided following the appendix.
