Download or read book Response of Guyed Offshore Towers to Stochastic Loads in the Presence of Steady Current written by Sigurdur Brynjolfsson and published by . This book was released on 1987 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: The validity of the widely used stochastic linearization method for analysing the response of guyed towers to stochastic loads is investigated. The governing equations of a guyed tower have two main sources of nonlinearities, fluid-structure interaction and the restoring force of the cables. In this study, two models are considered. First, a linearized single degree of freedom (SDOF) model of a guyed tower is developed using the stochastic linearization approach. It is solved in the frequency domain, giving the statistical response of the guyed tower to random waves and earthquake loading. The results are compared to the response statistics of a time simulation of a single degree of freedom system that fully incorporates the nonlinearities of the cable system and the fluid-structure interaction. Second, the dynamic response of a multiple degree of freedom (MDOF) model of a guyed offshore tower to stochastic earthquake loads and steady uniform current is investigated. The nonlinear cable stiffness and the fluid-structure interaction were again linearized using the stochastic linearization method. Numerical results for several load cases are presented and discussed. The displacement statistics from the MDOF linear analysis were compared to the statistics of the SDOF time simulation that fully incorporated the nonlinearities of the structure. The increased damping of the structure with increasing current was found to significantly reduce the stochastic forces and moments of the structure. The SDOF model is adequate for predicting statistics of displacements, but a MDOF model is needed to accurately predict statistics of maximum moments in the tower. It is found that the results from the linearized model agree reasonably well with the results from the time simulation of the fully nonlinear system. The computer time using the stochastic linearization approach is several order of magnitude less than for a conventional time simulation method. It is therefore justifiable to use this method in the early design stages of guyed towers.

Download or read book Dynamic Analysis and Design of Offshore Structures written by Srinivasan Chandrasekaran and published by Springer. This book was released on 2017-10-12 with total page 449 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: A classic work of American literature that has not stopped changing minds and lives since it burst onto the literary scene, The Things They Carried is a ground-breaking meditation on war, memory, imagination, and the redemptive power of storytelling. The Things They Carried depicts the men of Alpha Company: Jimmy Cross, Henry Dobbins, Rat Kiley, Mitchell Sanders, Norman Bowker, Kiowa, and the character Tim O’Brien, who has survived his tour in Vietnam to become a father and writer at the age of forty-three. Taught everywhere—from high school classrooms to graduate seminars in creative writing—it has become required reading for any American and continues to challenge readers in their perceptions of fact and fiction, war and peace, courage and fear and longing. The Things They Carried won France's prestigious Prix du Meilleur Livre Etranger and the Chicago Tribune Heartland Prize; it was also a finalist for the Pulitzer Prize and the National Book Critics Circle Award.
Download or read book Strengthening Forensic Science in the United States written by National Research Council and published by National Academies Press. This book was released on 2009-07-29 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scores of talented and dedicated people serve the forensic science community, performing vitally important work. However, they are often constrained by lack of adequate resources, sound policies, and national support. It is clear that change and advancements, both systematic and scientific, are needed in a number of forensic science disciplines to ensure the reliability of work, establish enforceable standards, and promote best practices with consistent application. Strengthening Forensic Science in the United States: A Path Forward provides a detailed plan for addressing these needs and suggests the creation of a new government entity, the National Institute of Forensic Science, to establish and enforce standards within the forensic science community. The benefits of improving and regulating the forensic science disciplines are clear: assisting law enforcement officials, enhancing homeland security, and reducing the risk of wrongful conviction and exoneration. Strengthening Forensic Science in the United States gives a full account of what is needed to advance the forensic science disciplines, including upgrading of systems and organizational structures, better training, widespread adoption of uniform and enforceable best practices, and mandatory certification and accreditation programs. While this book provides an essential call-to-action for congress and policy makers, it also serves as a vital tool for law enforcement agencies, criminal prosecutors and attorneys, and forensic science educators.

Download or read book Dynamic Loading and Design of Structures written by Andreas Kappos and published by CRC Press. This book was released on 2001-10-11 with total page 394 pages. Available in PDF, EPUB and Kindle. Book excerpt: Until now, information on the dynamic loading of structures has been widely scattered. No other book has examined the different types of loading in a comprehensive and systematic manner, and looked at their signficance in the design process. The book begins with a survey of the probabilistic background to all forms of loads, which is particularly important to dynamic loads, and then looks at the main types in turn: wind, earthquake, wave, blast and impact loading. The relevant code provisions (Eurocode and UBC American) are detailed and a number of examples are used to illustrate the principles. A final section covers the analysis for dynamic loading, drawing out the concepts underlying the treatment of all dynamic loads, and the corresponding modelling techniques. Throughout there is a focus on the modelling of structures, rather than on classical structural dynamics.
