For many years, engineers have used matrix methods for structural analysis. Although these methods are the most efficient for structural analysis, it is the author’s opinion that students taking their first course in this field should also be familiar with some of the more important classical methods. Practicing the application of these methods will deepen their understanding of the basic science of engineering, namely statics and mechanics of materials. In addition, thinking about and applying the various methods in a clear and orderly manner will further improve one’s problem-solving skills.
Solving problems in this manner allows one to better understand how loads are transferred through the structure and to more fully understand how the structure deforms under load. Finally, the classical method provides a means of checking computer results rather than simply relying on the output generated.
This book (structural analysis) is intended to provide students with a clear and thorough introduction to the theory and application of structural analysis as it applies to trusses, beams, and frames. Emphasis is placed on developing both structural modeling and analysis skills and providing realistic applications encountered in professional practice.
The content of each chapter is divided into sections with specific topics grouped under title headings. Discussions related to specific theories are brief but thorough. In most cases, a “Procedures of Analysis” guide follows, providing students with a summary of key concepts and a systematic approach to applying the theory.
About the Book
This book is divided into three parts. Part1 consists of seven chapters covering classical analytical methods for statically determined structures.
Chapter1 discusses the various types of structural forms and loads. Chapter2 discusses the determination of forces at statically determined beam and frame supports and joints. In Chapter3, various types of statically determined trusses are analyzed, and in Chapter4, shear and bending moment functions and diagrams for beams and frames are presented. Chapter5 presents the analysis of simple cable and arch systems, and Chapter6 discusses the lines of influence for beams, girders, and trusses. Finally, in Chapter7, several general techniques for the approximate analysis of statically indeterminate structures are discussed.
The second part of the book covers the analysis of statically indeterminate structures in six chapters. In Chapter8, geometric methods for calculating deflections are discussed. In Chapter9, energy methods for determining deflections are discussed. Chapter10 deals with the analysis of static indeterminate structures using the force analysis method, in addition to a discussion of influence lines for beams. Then, Chapter11 discusses the displacement method consisting of the gradient-deflection method, and Chapter12 discusses moment distributions. Finally, Chapter13 considers beams and frames with non-columnar members.
