Design And Performance Of Tall Buildings For Wind

Design and Performance of Tall Buildings for Wind, MOP 143, provides a framework for the design of tall buildings for wind, based on the current state-of-practice in tall building structural design and wind tunnel testing.

Prepared by the Task Committee for the Design and Performance of Tall Buildings of the Structural Engineering Institute of ASCEDesign and Performance of Tall Buildings for Wind, MOP 143, provides a framework for the design of tall buildings for wind. This MOP presents detailed guidance on industry standard practices and design approaches that complement current literature, model codes, and standards. The performance of tall buildings in wind depends on a combination of wind climate, loading effects, structural system, and damping. MOP 143 provides recommendations on setting and achieving performance objectives, including Selection of the wind loading mean recurrence interval (MRI) for serviceability; Establishment of performance objectives and acceptance criteria; Guidance on modeling building structural properties such as stiffness and damping; andModeling of uncertainties in wind climate, wind loading, and other effects.MOP 143 will be a valuable resource for structural engineers, wind engineering consultants, architects, and other stakeholders with a vested interest in design of tall buildings.

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.

ASCE 7 is the US standard for identifying minimum design loads for buildings and other structures. ASCE 7 covers many load types, of which wind is one. The purpose of this book is to provide structural and architectural engineers with the practical state-of-the-art knowledge and tools needed for designing and retrofitting buildings for wind loads. The book will also cover wind-induced loss estimation. This new edition include a guide to the thoroughly revised, 2010 version of the ASCE 7 Standard provisions for wind loads; incorporate major advances achieved in recent years in the design of tall buildings for wind; present material on retrofitting and loss estimation; and improve the presentation of the material to increase its usefulness to structural engineers. Key features: New focus on tall buildings helps make the analysis and design guidance easier and less complex. Covers the new simplified design methods of ASCE 7-10, guiding designers to clearly understand the spirit and letter of the provisions and use the design methods with confidence and ease. Includes new coverage of retrofitting for wind load resistance and loss estimation from hurricane winds. Thoroughly revised and updated to conform with current practice and research.

"The purpose of this book is to advance the wind design of tall buildings, enabling the performance-based design, review, acceptance, and construction of buildings using analyses, materials, structural systems, and devices that may or may not be covered by the prescriptive provisions of today's building codes"--

This second edition of Designing Tall Buildings, an accessible reference to guide you through the fundamental principles of designing high-rises, features two new chapters, additional sections, 400 images, project examples, and updated US and international codes. Each chapter focuses on a theme central to tall-building design, giving a comprehensive overview of the related architecture and structural engineering concepts. Author Mark Sarkisian, PE, SE, LEED® AP BD+C, provides clear definitions of technical terms and introduces important equations, gradually developing your knowledge. Projects drawn from SOM’s vast portfolio of built high-rises, many of which Sarkisian engineered, demonstrate these concepts. This book advises you to consider the influence of a particular site's geology, wind conditions, and seismicity. Using this contextual knowledge and analysis, you can determine what types of structural solutions are best suited for a tower on that site. You can then conceptualize and devise efficient structural systems that are not only safe, but also constructible and economical. Sarkisian also addresses the influence of nature in design, urging you to integrate structure and architecture for buildings of superior performance, sustainability, and aesthetic excellence.

Generally, the taller the structure the more important the role of wind. Yet most designers of tall building structures lack a basic understanding of the response of these structures to wind loading. Drawing together the relevant structural design principles with code or wind tunnel specified loads can deliver efficient and cost-effective structural designs which offer an appropriate degree of service performance and ultimate reliability. Analysing the dynamic behaviour of existing flexible building structures under wind loading is essential for their management over a long service life. All of this requires knowledge and understanding beyond a traditional structural engineering background. This heavily practical book formalizes a great deal of information and understanding from the authors’ practice and their work in developing AISC, ACI and ASCE codes of practice.

Prepared by the Council on Tall Buildings and Urban Habitat of ASCE. This report examines the loads to which tall buildings are subjected so that engineers can precisely define the related structural elements that are necessary before translating a client's needs into a safe design. The report explores five different classes of loads?gravity loads and temperature affects, earthquake loads, wind loading and wind effects, fire, and accidental loads?as well as quality control and overall safety considerations.ØSteel buildings, which hold the record for height, tax the designer's ingenuity to provide adequate resistance to lateral loading. Concrete buildings are both more numerous and widely distributed, and for them vertical gravity loads may be the chief problem. Both steel and concrete buildings and lateral and vertical loads are addressed. Other subjects covered include: dead, live, cyclic snow, construction, and combined loads; code requirements; meteorological and environmental factors in design; firefighting provisions; and modeling. Contributions came from more than 800 contributors, all international and professional and heavily representing design and industrial firms. Condensed references follow each chapter, and a glossary is included.
