This book was released on 2012-12-06 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1 957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna tional publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 28 (thesis year 1 983) a total of 10,661 theses titles from 26 Canadian and 197 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work. While Volume 28 reports theses submitted in-1983, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.

This book was released on 2001-01-01 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: Prepared by the Task Committee on the Dynamic Response of Lattice Towers of the Technical Committee on Special Structures and the Technical Administrative Committee on Metals of the Structural Engineering Institute of ASCE. This report is a compilation and clarification of current methodologies for the dynamic response of communication towers in a single source. The information regarding the dynamic response of lattice towers is currently scattered throughout the literature, making it difficult for the practicing engineer to obtain the information necessary for design purposes. Both self-supporting lattice towers and guyed lattice masts (guyed lattice towers) are included. Topics include: Ødynamics of cables and towers, Ødynamic analysis, Øwind loads and response, Øseismic input and response, and Øvibration control.

Download or read book Structural Optimization Under Stability and Vibration Constraints written by M. Zyczkowski and published by Springer. This book was released on 2014-05-04 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: Optimal design of structures leads, as a rule, to slender and thin-walled shapes of the elements, and such elements are subject to the loss of stability. Hence the constraints of structural optimization usually include stability constraints, expressed by some eigenvalues. Optimal design under vibration constraints belongs also to optimization with respect to eigenvalues. The present volume gives a short introduction to structural optimization and then pays particular attention to multimodal optimization under stability and vibration constraints, both in elastic and inelastic range. One part is devoted to thin-walled bars optimized for interactive buckling with imperfections taken into account. The volume is of interest both to researchers and design engineers: it covers the most recent results of multimodal and interactive optimization, allowing for inelastic behaviour of structures, and the constraints discussed appear in almost all problems of engineering design.

Book excerpt: Torres estaiadas são, em geral, estruturas bastante leves e esbeltas e que apresentam comportamento eminentemente não -linear. Assim, a análise de sua estabilidade sob cargas estáticas e dinâmicas é essencial para se ter um projetoeconômico e seguro. Neste trabalho estuda-se a estabilidade estática e dinâmica de um modelo plano de torre estaiada. Especial atenção é dada à modelagem dos estais, que são modelados como elementos de mola (linear ou não -linear) ou como cabos inextensíveis. Faz-se, com base no princípio da energia potencial mínima, um estudo da carga crítica e do caminho pós-crítico. Um estudo paramétrico minucioso permite analisar a influência dos diversos parâmetros físicos e geométricos na estabilidade da torre e chegar às melhores configurações para os estais. Na análise dinâmica atenção especial é dada ao estudo paramétrico dafreqüência natural. Com base nos resultados da análise estática, analisa-se também o comportamento global da torre em vibração livre e forçada. Em virtude das não linearidades, verifica-se que a torre pode apresentar diversos comportamentos típicos de sistemas não -lineares tais como saltos, bifurcações de período e caos.

Book excerpt: Guyed towers are used for communication purposes and are frequently designed to heights of 300 meters (1000 feet). A guyed tower is a non-linear structure in which the mast, typically consisting of multiple truss members is supported laterally at several points by inclined guy cables. The guy cables are anchored to a foundation and are pre-tensioned. Wind induced vibrations may result in a fatigue failure of a guy anchor linkage or a cable, ultimately causing the collapse of an entire tower. In addition, excessive deflections or vibrations may interfere with communications and control systems resulting in serviceability failure. According to design standards, a basic understanding of the dynamic characteristics of guyed towers is important. This study develops an easy to use software package, aimed at practicing engineers, to determine free-vibration characteristics (natural frequencies and mode shapes) of guyed towers. The analysis presented herein employs the finite element method to determine the naturalfrequencies and mode shapes of guyed towers. The structural system is broken down into two main components, the tower mast and guy cables. Utilizing an equivalent beam-column analysis that take into consideration different lacing patterns, the mast is modelled as a beam-column with equivalent properties. A three-dimensional cable finite element following a catenary or parabolic profile is used to model guy cables. Several comparisons are made to ensure the accuracy of the cable element and the guyed tower model. Selected numerical results are presented for natural frequencies and mode shapes of a few representative towers. The influence of cable tension, lacing pattern of the mast and configuration of guy cables is also examined. The software package can be extended to include forced vibration response through the modal superposition method.

Download or read book Wind Forces in Engineering written by Peter Sachs and published by Elsevier. This book was released on 2013-10-22 with total page 411 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wind Forces in Engineering, Second Edition covers the various aspects, principles, and engineering applications of wind forces. This book is composed of 10 chapters and starts with an introduction to the history of wind forces. The subsequent chapters consider the wind speeds for various topographies; particular "shape factors" for general and special structures; oscillatory wind forces of a random or single-frequency type; and the dynamic response of structures to oscillatory wind forces. Other chapters deal with specific structures, such as buildings, bridges, towers, radar antennas, for static and dynamic wind loadings. The final chapter provides the Code of Practice which has been republished since 1972, including those for Australia, Canada, Great Britain and the U.S.A. These codes do not provide similar responses and are all essentially in a transitional state between the old static force concept and an improved statistical analysis to be based on more experimental evidence. This book will prove useful to engineers and researchers.
