The current trend of building more streamlined structures has made stability analysis a subject of extreme importance. It is mostly a safety issue because Stability loss could result in an unimaginable catastrophe. Written by two authors with a combined 80 years of professional and academic experience, the objective of Stability of Structures: Principles and Applications is to provide engineers and architects with a firm grasp of the fundamentals and principles that are essential to performing effective stability analysts.

Concise and readable, this guide presents stability analysis within the context of elementary nonlinear flexural analysis, providing a strong foundation for incorporating theory into everyday practice. The first chapter introduces the buckling of columns. It begins with the linear elastic theory and proceeds to include the effects of large deformations and inelastic behavior. In Chapter 2 various approximate methods are illustrated along with the fundamentals of energy methods. The chapter concludes by introducing several special topics, some advanced, that are useful in understanding the physical resistance mechanisms and consistent and rigorous mathematical analysis. Chapters 3 and 4 cover buckling of beam-columns. Chapter 5 presents torsion in structures in some detail, which is one of the least well understood subjects in the entire spectrum of structural mechanics. Strictly speaking, torsion itself does not belong to a topic in structural stability, but needs to be covered to some extent for a better understanding of buckling accompanied with torsional behavior. Chapters 6 and 7 consider stability of framed structures in conjunction with torsional behavior of structures. Chapters 8 to 10 consider buckling of plate elements, cylindrical shells, and general shells. Although the book is primarily devoted to analysis, rudimentary design aspects are discussed.

Balanced presentation for both theory and practice Well-blended contents covering elementary to advanced topics Detailed presentation of the development

Introduction to Vibration in Engineering is a concise text that helps students master the fundamentals of vibration. Students develop a solid understanding of single-degree-of-freedom systems that can be used as building blocks to tackle more difficult and general multi-degree-of-freedom systems. The text also introduces the Lagrange equation approach, which can be used to construct equations of motion for complex systems.Dedicated chapters cover the dynamic responses of single-degree-of-freedom and multi-degree-of-freedom systems, dynamic stability, vibration absorbers, vibration of slender bodies, modal identification, finite element modeling, and more. Each chapter features problem sets that challenge students to apply what they have learned.The fourth edition features new equations, updated figures, refined explanations and question prompts, and new information on the modal approach to damped MDOF systems and the assembly of global mass matrix, stiffness matrix, and load vector.Designed for undergraduate seniors and first-year graduate students, Introduction to Vibration in Engineering is ideal for courses in aerospace and mechanical engineering. Use of the text requires sophomore-level mathematics ability, including elementary linear algebra.
