Preface
PURPOSE AND FAMILY This book covers several related topics: displacement methods and matrix design, theory and analysis of structural properties, as well as applications in seismic engineering and seismic architecture. As computer technology advances and buildings become increasingly larger, the dynamic behavior of these structures needs to be examined using modern matrix-based methods. Correct analysis and computational methods of structural problems depend on several important factors: structural modeling, material properties, structural equations and computational techniques.
The features of this book can be summarized as follows. Three structural methods were studied: solid mass, fixed mass, and distributed mass. Practical tools are offered in two categories: deleting and active. Damping is done in two ways: balanced and unbalanced. The hysteretic behavior was examined with eight models suitable for different building materials such as steel and reinforced concrete. Loading includes many time-dependent factors of interest, such as dynamic elasticity, impact loading, free and transient vibrations, and seismicity of the ground. Numerical techniques emphasize two aspects: eigen solution and numerical integration. The first includes both basic and advanced techniques for the five dominant styles; the second contains five known combinations. Architecture is used to describe the architecture of the building code. Representative codes are discussed to show their similarity to the variant.
This book is intended for both graduate students and students in engineering, mechanics, and aeronautics. It is also designed as an application tool. Six planning principles served as a guide in the preparation of this document. Discrete elements as well as vector analysis and complex variables are repeated as necessary.
2. Numerical examples are given step by step. This helps present the figures and explain the real picture, helping the reader understand how to relate their engineering activities.
3. Each chapter covers a specific topic. Each chapter has a progression from basic to advanced; For example, natural solution methods are discussed in Chapter 2, numerical integration techniques in Chapter 7, and hysteresis models in Chapter 9. These methods can help the reader follow the lesson and the teacher select materials for class presentations.
4. The main sections cover everything. For example, three structural methods for the absorption and coupling of vibrations with longitudinal, bending and torsional forces have been examined. Vibrations range from torsional bending to bending and shear to inertial deformation, P-5. 3D architectural structures are displayed in one dimension. Comprehensive information is developed for membership, integration and coordination of global activities in 3D. In particular, building systems are analyzed in detail in terms of floor membranes, beams, girders, columns, sliding walls and complex zone connections. These elements are not grouped into a structured text or static analysis text; this book could fill the last.6. The examples are intended to help the reader understand the concepts presented. The content of the book consists of 114 examples and a question-answer list for each chapter. A detailed guide is available. Computer programs are used to interpret the numerical values presented in the text.
SOFTWARE AND EDUCATION THOUGHTS The range of text and ID units that can be used in the second semester of the course is clear. 1-6. Episodes first season, 7-10. The episodes constitute the second season. Basic and advanced topics in the chapters are marked as Part A and Part B respectively. If the textbook is used in one semester, Section B may be omitted at the discretion of the instructor.
The content of the text can be summarized as follows. Part I introduces one degree of freedom (d. O.F.) system. Different response behaviors are shown for different types of tribute. Common troubleshooting methods are explained.
Chapter 2 is devoted to the response behavior of d. Without removing the O.F. system. The importance of the different mechanisms involved in this behavior is central, and a full understanding of the matrix is the aim of this chapter. Eigen solution methods are taken into consideration for computational efficiency and productivity. These methods include deterministic, regression, Jacobian, Choleski decomposition, and Sturm decomposition. Analysis of the results ranges from general problems to single matrices with symmetric matrices with different frequencies, as well as zeros and eigenvalues with multiple frequencies in different areas of the architecture.
Chapter 3 examines the properties of reduction and discontinuity. Considering both types of deletion, different methods for eigenvalues and results are included and the results are compared.
Chapter 4 presents the basics of a general distributed system. Emphasis is placed on dynamic dynamics, dynamic-emotional dynamics in turbulent uncertainty, and short-term oscillations in general forcing processes, including seismic excitation and inertia.
Chapter 5 continues the topic of distributed systems and also covers long-term, elastic, and torsional coupling vibrations. In addition, bending and cutting, rotation inertia and P- vibration of cage beams, elastic frames and cage systems.
Chapter 6 introduces the general finite element model. Processes and plates are examined with emphasis on isoperimetric finite element formulation. Advanced articles include views of Tymoshenko members and the impact of P-11. Note that the distributed system model in Chapter 4 provides a lower bound on the eigen solution, while the model in Chapter 6 provides a solution between the single mass and the general model. Therefore, the results are comparable.
Chapter 7 covers seismic properties and ground motions as well as structural analysis and design. Popular statistical methods such as Newmark’s, Wilson-0, and Runge-Kurta fourth order are presented along with the results of the problem and nonlinear behavior. Processes are created to create simple and perfect solutions and then the design is made. This section shows six sections of the field: three modified and three returning. The resulting model is then adjusted to represent the impact of these components on the structural results. Combination methods such as CQC (Complete Quadratic Combination) are presented in detail.
