These examples pave the way to more accurately simulate the behavior of various types of structures. The essential topics covered include principles of structural dynamics applied to particles, rigid and deformable bodies, thus enabling the formulation of equations for the motion of any structure. Covers the tools and techniques needed to build realistic modeling of actual structures under dynamic loads Provides the methods to formulate the equations of motion of any structure, no matter how complex it is, once the dynamic model has been adopted Provides carefully worked-out examples that are solved using recent numerical methods Includes simple computer algorithms for the numerical solution of the equations of motion and respective code in FORTRAN and MATLAB
This book is concerned with the static and dynamic analysis of structures. Specifi cally, it uses the stiffness formulated matrix methods for use on computers to tackle some of the fundamental problems facing engineers in structural mechanics. This is done by covering the Mechanics of Structures, its rephrasing in terms of the Matrix Methods, and then their Computational implementation, all within a cohesivesetting. Although this book is designed primarily as a text for use at the upper-undergraduate and beginning graduate level, many practicing structural engineers will find it useful as a reference and self-study guide. Several dozen books on structural mechanics and as many on matrix methods are currently available. A natural question to ask is why another text? An odd devel opment has occurred in engineering in recent years that can serve as a backdrop to why this book was written. With the widespread availability and use of comput ers, today's engineers have on their desk tops an analysis capability undreamt of by previous generations. However, the ever increasing quality and range of capabilities of commercially available software packages has divided the engineering profession into two groups: a small group of specialist program writers that know the ins and outs of the coding, algorithms, and solution strategies; and a much larger group of practicing engineers who use the programs. It is possible for this latter group to use this enormous power without really knowing anything of its source.

This book presents a series of integrated computer programs in Fortran-90 for the dynamic analysis of structures, using the finite element method. Two dimensional continuum structures such as walls are covered along with skeletal structures such as rigid jointed frames and plane grids. Response to general dynamic loading of single degree freedom systems is calculated, and the author also examines multi degree of freedom systems (including earthquake analysis). Each chapter covers a different aspect of analytic theory and the corresponding program segments. It will be an essential tool for practising structural and civil engineers, whilst also being of interest to academics and postgraduate students.

This book introduces readers to various types of offshore platform geometries. It addresses the various environmental loads encountered by these structures, and provides detailed descriptions of the fundamentals of structural dynamics in a classroom style, helping readers estimate damping in offshore structures and grasp these aspects’ applications in preliminary analysis and design. Basic concepts of structural dynamics are emphasized through simple illustrative examples and exercises. Design methodologies and guidelines, which are FORM based concepts, are explained through a selection of applied sample structures. Each chapter also features tutorials and exercises for self-learning. A dedicated chapter on stochastic dynamics helps students to extend the basic concepts of structural dynamics to this advanced domain of research. Hydrodynamic response of offshore structures with perforated members is one of the most recent research applications, and has proven to be one of the most effective means of retrofitting offshore structures. In addition, the book integrates the concepts of structural dynamics with the FORM-evolved design of offshore structures, offering a unique approach. This new edition is divided into seven chapters, each of which has been updated. Each chapter also includes a section on frequently asked Questions and Answers (Q&A), which enhances understanding of this complex subject through easy and self-explanatory text. Furthermore, the book presents valuable content with respect to new and recent research carried out by the author in structural dynamics. All numeric examples have been re-checked with more additional explanations. New exercises have been added to improve understanding of the subject matter. Computer coding is also included (wherever possible) to aid computer-based learning of the contents of the book. The book can serve as a textbook for senior undergraduate and graduate courses in civil, structural, applied mechanics, mechanical, aerospace, naval architecture and ocean engineering programs. The book can also serve as a text for professional learning and development programs or as a guide for practicing and consulting offshore structural engineers. The contents of this book will be useful to graduate students, researchers, and professionals alike.

"Summarizes the theoretical development of the finite elements and numerical methods used in the latest versions of the SAP and ETABS programs. Although only a minimum mathematical and programming background is required to completely understand the book, a thorough understanding of the physical behavior of real structures is essential"--Provided by publisher.
Dynamic Analysis of Offshore Structures appraises offshore structures, particularly the major sources of uncertainty in the design process. The book explains the fundamentals of probabilistic processes, the theory or analysis of sea states, and the random-vibration approach to structural response. The text describes the hydrodynamics of water waves, wave forecasting, and the statistical parameters associated with sea-states. The investigator can use Morison's equation to calculate the impact of wave forces acting on slender members such as on lattice-type structures. Or he can employ the diffraction theory to calculate wave forces acting on large-diameter bodies such as concrete gravity-type structures. Other environmental forces he should be concerned with are the effects of currents and winds. The book examines the theory of vibration (including the spectral approach), the theory of vibration on multi-degree-of-freedom structures, matrix analysis of structural response, problems of fatigue, and soil-structure interaction. The book notes the importance of the method of analysis used, with emphasis on the following: dynamic analysis, frequency domain, and linearization of drag. Two types of analysis follow linearization of drag: deterministic analysis (applied in a series of design waves which uses the long-term exceedance diagram for fatigue); or probabilistic analysis (used to study the behavior of the structure during the extreme design storm and its long term behavior for a range of sea states). The book can prove useful for structural, civil, or maritime engineers, as well as for students in one-year courses in offshore structure analysis at the postgraduate or final-year undergraduate level.
The purpose of this publication is to summarize the computational methods that are used in many modern computer programs for the seismic analysis of three-dimensional structural systems. After more than thirty years of working closely with structural engineers, it has become apparent that a need exists for a book on the Three Dimensional Dynamic Analysis of Structures. The necessary computational background to conduct seismic computer analyses of large structures needs to be simplified and understood. In addition, problems associated with the creation of complex three-dimensional computer models and the interpretation of results is emphasized in this book.
Bachelor Thesis from the year 2013 in the subject Engineering - Civil Engineering, grade: AA, Gujarat University (Gujarat Technological University), course: Final Year Project, language: English, abstract: Ever since the existence of mankind, it has noticed a remarkable advancement in field of science and technology. Traditional hand weaving methods have been replaced by modern and speedy looms machine. With faster production rate, these machines proved to be a boon for textile manufacturers. However, they come with an unnoticed problem of “vibration”. Hence, there arises a need to study the effects of vibrations on the structural as well as non structural components of the building. Here in this project, an attempt has been made to study the dynamic behavior of a structure for looms industry subjected to vibration due to operations of looms machine; by changing its various parameters. With an increase in demand of textile, more and more looms machines are being installed every day. While designing the structure to house these looms it becomes incumbent upon the designer to curtail the amplitude of vibrations within the permissible limits. One must also make sure that the frequency of structure is separated for operating frequency of machine by a good margin, so that the “Resonance Condition” can be avoided. The looms machine fall under the category of reciprocating machine and have medium operating speed ranging from 100 rpm to 180 rpm. The main source of vibration is the Beating-Up motion. This generates a Harmonic Load due to the unbalanced force caused by the reciprocating sley movement. Hence, the designing of structure for looms industry is a complex process which needs prime considerations. The cost of dynamic analysis of these structure is paramount, hence a small fraction of amount is being spent might lead to inadequately constructed structures which may result in failure and shut downs, exceeding many times the cost of the capital investment required for properly designed and built structure. Now, in such a case by executing parametric study, one can decide which parameter out of many is most sensitive to odd results, so that by varying those parameters only results can be brought to the required level and do not affect other reliable results. An attempt is made in the thesis to carry out a parametric study by using software STAAD. Pro Following Parameters are studied in this thesis 1. Sizes of Column 2. Sizes of Beams 3. Story Height 4. Number of Stories Effect of remedial measures like: 1. Cross Bracing below Plinth Level 2. Full Length Jacketing of Columns 3. Partial Length Jacketing of Columns 4. Cross Tie-Beams 5. Haunches at the Junction
