Principles of Structural Design: Wood, Steel, and Concrete, Second Edition by Ram S. Gupta.
Preface: this book intends to meet the need that exists for an elementary level textbook in structural design. It is a complete book. The book has a code-connected focus. Since publication of the first edition in 2010, all codes and standards have undergone revisions. The International Building Codes and the International Residential Codes were updated in 2012. The American Society of Civil Engineers (ASCE) has revised the Minimum Design Loads for Buildings and Other Structures to ASCE 7-10. The American Wood Council has published National Design Specifications (NDS) 2012 for wood design.
The American Institute of Steel Construction (AISC) has updated the Steel Construction Manual and the Seismic Design Manual to 2010 Standards and Specifications. The American Concrete Institute (ACI) has come up with new ACI 380-2011 Building Code Requirements for Structural Concrete. All these changes have necessitated an accelerated revision of the book. While undertaking this task, the text material has been thoroughly reviewed and expanded, including inclusion of a new chapter on concrete design. The book retains its original feature; it is suitable for a combined design coursework in wood, steel, and concrete. It is a self-contained book that includes all essential material—the section properties, design values, reference tables, and other design aids required to accomplish complete structural designs according to the codes. Unlike other books, the requirements of the separate documents pertaining to the codes and standards of the issuing agencies are not a prerequisite with this book. The book is appropriate for an academic program in architecture, construction management, general engineering, and civil engineering, where the curriculum provides for a joint coursework in wood, steel, and concrete design.
The book has four sections, expanded into 17 chapters. Section I, comprising Chapters 1 through 5, enables students to determine the various types and magnitude of loads that will be acting on any structural element and the combination(s) of those loads that will control the design. ASCE 7-10 has made major revisions to the provisions for wind loads. In Section I, the philosophy of the load and resistance factor design and the unified approach to design are explained. Wood design in Section II from Chapters 6 through 8 covers sawn lumber, glued laminated timber, and structural composite or veneer lumber, which are finding increased application in wood structures. The NDS 2012 has modified the format conversion factors and has also introduced some new modification factors. First, the strength capacities in accordance with the NDS 2012 for tensile, compression, and bending members are discussed and the basic designs of these members are performed. Subsequently, the designs of columns, beams, and combined force members are presented, incorporating the column stability and beam stability and other factors. The connection is an important subject because it is often neglected and proves to be a weak link of a structure.
The dowel-type connections (nails, screws, and bolts) have been presented in detail, together with the complete set of tables of the reference design values. Section III from Chapters 9 through 13 deals with steel structures. This covers the designs of tensile, compression, bending members and the braced and unbraced frames according to the AISC specifications and the designs of open-web steel joists and joist girders according to the standards of the Steel Joists Institute. AISC 2010 has made some revisions to the sectional properties of certain structural elements. It has also made changes in the procedure to design the slip-critical connection. Similar to wood design, a separate chapter considers shear connection, tension connection, and moment-resisting bolted and welded connections and various types of frame connections.
Section IV from Chapters 14 through 17 covers the reinforced concrete design. A new chapter on T beams and doubly reinforced beams has been added. In concrete, there is no tensile member and shear is handled differently as discussed in Chapter 16.
