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: Although Architecture and Structural Engineering have both had their own historical development, their interaction has led to many fascinating and delightful structures over time. To bring this interaction to a higher level, there is the need to stimulate the inventive and creative design of architectural structures and to persuade architects and s

Download or read book Computational Wind Engineering 1 written by S. Murakami and published by Elsevier. This book was released on 2014-06-28 with total page 925 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this volume is to explore the challenges posed by the rapid development of Computational Fluid Dynamics (CFD) within the field of engineering. CFD is already essential to research concerned with fluid flow in civil engineering, and its further potential for application in wind engineering is highly promising. State-of-the-art papers from all over the world are contained here, illuminating the present parameters of the field, as well as suggesting fruitful areas for further research. Eleven papers have been contributed by invited speakers outstanding in the fields of CFD and wind engineering. This volume will serve as a vehicle to promote further development in computational wind engineering.
