Book Description
Wind forces from extreme wind events are the dominant loading for many parts of the world, exacerbated by climate change and the continued construction of tall buildings and structures. This authoritative source, for practising and academic structural engineers and graduate students, ties the principles of wind loads on structures to the relevant aspects of meteorology, bluff-body aerodynamics, probability and statistics, and structural dynamics. This new edition covers: Climate change effects on extreme winds – particularly those from tropical cyclones, hurricanes and typhoons Modelling of potential wind vulnerability and damage Developments in extreme value probability analysis of extreme wind speeds and directions Explanation of the difference between ‘return period’ and ‘average recurrence interval’, as well as ‘bootstrapping’ techniques for deriving confidence limits Wind over water, and profiles and turbulence in non-synoptic winds An expanded chapter on internal pressures produced by wind for various opening and permeability scenarios Aerodynamic shaping of high- and low-rise buildings Recent developments in five major wind codes and standards A new chapter on computational fluid dynamics (CFD), as applied to wind engineering A greatly expanded appendix providing the basic information on extreme wind climates for over 140 countries and territories Additional examples for many chapters in this book

Book Description
Proceedings of a session at the ASCE Convention, held in Seattle, Washington, April 8, 1986. Sponsored by the Aerodynamics Committee of the Aerospace Division and the Wind Effects Committee of the Structural Division of ASCE. This collection contains six papers examining the motions of buildings produced by wind. The trend towards higher structural efficiency and lower cost has resulted in a generation of lighter and more flexible buildings with a lower inherent capacity for energy dissipation or damping. Unfortunately, this trend has produced structures that are more sensitive to the dynamic action of wind. The emphasis in the design of modern tall buildings has therefore shifted to requirements that control building movements or drift and that limit wind-induced accelerations. Two papers deal with the action of wind on two important tall buildings where designers relied on wind tunnel model tests for information on wind-induced loads and building motions. The design of the Columbia Seafirst Center took advantage of economies possible as a result of wind tunnel studies., and viscoelastic dampers were added to limit the building's motion and wind-induced acceleration. The recorded response of the Allied Bank Plaza during Hurricane Alicia is an extremely important contribution to the understanding of the action of wind on tall buildings; this is the only existing record of the response of a major building under the action of design winds. Another paper discusses a survey of structural damping found in tall buildings, presenting typical damping values for steel and concrete buildings and discussing the variability of such estimates and its implication on design. The final papers consider damping systems that can be added to tall buildings in order to limit their motion. The use of tuned mass dampers and viscoelastic damping units is discussed and examples are presented to show their practical effectiveness. The viscoelastic dampers used in the Columbia Seafirst Center are described.

Book Description
Provides structural engineers with the knowledge and practical tools needed to perform structural designs for wind that incorporate major technological, conceptual, analytical and computational advances achieved in the last two decades. With clear explanations and documentation of the concepts, methods, algorithms, and software available for accounting for wind loads in structural design, it also describes the wind engineer's contributions in sufficient detail that they can be effectively scrutinized by the structural engineer in charge of the design. Wind Effects on Structures: Modern Structural Design for Wind, 4th Edition is organized in four sections. The first covers atmospheric flows, extreme wind speeds, and bluff body aerodynamics. The second examines the design of buildings, and includes chapters on aerodynamic loads; dynamic and effective wind-induced loads; wind effects with specified MRIs; low-rise buildings; tall buildings; and more. The third part is devoted to aeroelastic effects, and covers both fundamentals and applications. The last part considers other structures and special topics such as trussed frameworks; offshore structures; and tornado effects. Offering readers the knowledge and practical tools needed to develop structural designs for wind loadings, this book: Points out significant limitations in the design of buildings based on such techniques as the high-frequency force balance Discusses powerful algorithms, tools, and software needed for the effective design for wind, and provides numerous examples of application Discusses techniques applicable to structures other than buildings, including stacks and suspended-span bridges Features several appendices on Elements of Probability and Statistics; Peaks-over-Threshold Poisson-Process Procedure for Estimating Peaks; estimates of the WTC Towers’ Response to Wind and their shortcomings; and more Wind Effects on Structures: Modern Structural Design for Wind, 4th Edition is an excellent text for structural engineers, wind engineers, and structural engineering students and faculty.

Book Description
Since the 1960s, wind tunnel testing has become a commonly used tool in the design of tall buildings. It was pioneered, in large part, during the design of the World Trade Center Towers in New York. Since those early days of wind engineering, wind tunnel testing techniques have developed in sophistication, but these techniques are not widely understood by the designers using the results. As a direct result, the CTBUH Wind Engineering Working Group was formed to develop a concise guide for the non-specialist. The primary goal of this guide is to provide an overview of the wind tunnel testing process for design professionals. This knowledge allows readers to ask the correct questions of their wind engineering consultants throughout the design process. This is not an in-depth guide to the technical intricacies of wind tunnel testing, it focusses instead on the information the design community needs, including: a unique methodology for the presentation of wind tunnel results to allow straightforward comparison of results from different wind tunnel laboratories. advice on when a tall building is likely to be sufficiently sensitive to wind effects to benefit from a wind tunnel test background for assessing whether design codes and standards are applicable details of the types of tests that are commonly conducted descriptions of the fundamentals of wind climate and the interaction of wind and tall buildings This unique book is an essential guide for all designers of tall buildings, and anyone else interested in the process of wind tunnel testing for tall buildings.
