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.

Available in PDF, EPUB and Kindle. Book excerpt: An algorithm has been developed to calculate mode shapes and natural frequencies of taut cables with attached masses. The transcendental equations of motion are solved by an iterative technique that allows accurate calculation of extremely high mode numbers. The algorithm has been implemented as a FORTRAN program primarily as a tool in determining drag coefficients of submerged strumming cables; however, any taut cable can be analyzed. To assess the accuracy of the program, a simple experiment was conducted to determine the natural frequencies and mode shapes of a wire with attached masses driven sinusoidally by a shaker. The algorithm shows close agreement with the experimental data. (Author).

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.

Available in PDF, EPUB and Kindle. Book excerpt: Following on from the International Conference on Structural Engineering, Mechanics and Computation, held in Cape Town in April 2001, this book contains the Proceedings, in two volumes. There are over 170 papers written by Authors from around 40 countries worldwide. The contributions include 6 Keynote Papers and 12 Special Invited Papers. In line with the aims of the SEMC 2001 International Conference, and as may be seen from the List of Contents, the papers cover a wide range of topics under a variety of themes. There is a healthy balance between papers of a theoretical nature, concerned with various aspects of structural mechanics and computational issues, and those of a more practical nature, addressing issues of design, safety and construction. As the contributions in these Proceedings show, new and more efficient methods of structural analysis and numerical computation are being explored all the time, while exciting structural materials such as glass have recently come onto the scene. Research interest in the repair and rehabilitation of existing infrastructure continues to grow, particularly in Europe and North America, while the challenges to protect human life and property against the effects of fire, earthquakes and other hazards are being addressed through the development of more appropriate design methods for buildings, bridges and other engineering structures.

Available in PDF, EPUB and Kindle. Book excerpt: ENGINEERING ACOUSTICS NOISE AND VIBRATION CONTROL A masterful introduction to the theory of acoustics along with methods for the control of noise and vibration In Engineering Acoustics: Noise and Vibration Control, two experts in the field review the fundamentals of acoustics, noise, and vibration. The authors show how this theoretical work can be applied to real-world problems such as the control of noise and vibration in aircraft, automobiles and trucks, machinery, and road and rail vehicles. Engineering Acoustics: Noise and Vibration Control covers a wide range of topics. The sixteen chapters include the following: Human hearing and individual and community response to noise and vibration Noise and vibration instrumentation and measurements Interior and exterior noise of aircraft as well as road and rail vehicles Methods for the control of noise and vibration in industrial equipment and machinery Use of theoretical models in absorptive and reactive muffler and silencer designs Practical applications of finite element, boundary element and statistical energy analysis Sound intensity theory, measurements, and applications Noise and vibration control in buildings How to design air-conditioning systems to minimize noise and vibration Readers, whether students, professional engineers, or community planners, will find numerous worked examples throughout the book, and useful references at the end of each chapter to support supplemental reading on specific topics. There is a detailed index and a glossary of terms in acoustics, noise, and vibration.

Available in PDF, EPUB and Kindle. Book excerpt: Two of the most acclaimed reference works in the area of acoustics in recent years have been our Encyclopedia of Acoustics, 4 Volume set and the Handbook of Acoustics spin-off. These works, edited by Malcolm Crocker, positioned Wiley as a major player in the acoustics reference market. With our recently published revision of Beranek & Ver's Noise and Vibration Control Engineering, Wiley is a highly respected name in the acoustics business. Crocker's new handbook covers an area of great importance to engineers and designers. Noise and vibration control is one largest areas of application of the acoustics topics covered in the successful encyclopedia and handbook. It is also an area that has been under-published in recent years. Crocker has positioned this reference to cover the gamut of topics while focusing more on the applications to industrial needs. In this way the book will become the best single source of need-to-know information for the professional markets.
