This report represents the state-of-the-practice for wind load design at industrial facilities and is aimed at engineers familiar with design of industrial type structures.

This report provides state-of-the-practice guidelines for the computation of wind-induced forces on industrial facilities with structural features outside the scope of current codes and standards.

Prepared by theØTask Committee on Wind-Induced Forces and Task Committee on Anchor Bolt Design of the Petrochemical Committee of the Energy Division of ASCE. This report presents state-of-the-practice set of guidelines for the determination of wind-induced forces and the design of anchor bolts for petrochemical facilities. Current codes and standards do not address many of the structures found in the petrochemical industry. As a result, engineers and petrochemical companies have independently developed procedures and techniques for handling engineering issues such as the twoØcontained in this report. A lack of standardization in the industry has led to inconsistent structural reliability, however. This volume is intended for structural design engineers familiar with design of industrial-type structures.

These committee reports provide state-of-the-practice guidelines for the determination of wind induced forces and the design of headed, cast-in-place anchor bolts for petrochemical facilities. The basis and procedures for determining wind induced forces for enclosed structures and other conventional structures are addressed, in addition to load components such as force coefficients, tributary areas, and shielding for industrial-type structures and equipment. Topics include comparisons of current design practices, recommended guidelines, examples, and research needs of pipe racks, open frame structures, and pressure vessels. The second report evaluates current petrochemical industry anchor bolt design methods, proposed changes and new releases of design codes, and provides recommendations that supplement current codes for design of headed, cast-in-place anchor bolts. Subject areas include the current state of research, grades, fabrication and welding, corrosion, bolt configuration and dimensions, distribution of anchor bolt forces, checking critical modes of failure, pier design/reinforcing, pretensioning, and considerations for vibratory and seismic loads.

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.

Bridging the gap between wind and structural engineering, Wind Loading of Structures demonstrates the application of wind engineering principles to ensure maximum safety in a variety of structures. This book will assist the practising engineer in understanding the principles of wind engineering, and provide guidance on the successful design of structures for wind loading by gales, hurricanes, typhoons, thunderstorm downdrafts and tornados. The principles of meteorology, statistics and probability, aerodynamics and structural dynamics are covered in the first half of the book. The second half describes, qualitatively and quantitatively, the nature of wind loads on all types of structures, including low-rise and tall buildings, large stadium roofs, towers and chimneys, bridges, transmission lines, free-standing walls and roofs, and antennae. Special features include coverage of extreme winds in tropical and sub-tropical climates, wind-tunnel testing techniques, a summary of the wind climates of over sixty countries, and detailed coverage of internal as well as external wind pressures on buildings. A comparison is made of the provisions for wind loads in six major national and international codes and standards. Examples and case studies are given in each chapter that make the book suitable for supporting university graduate courses in wind loading and response.

Bridging the gap between wind and structural engineering, Wind Loading of Structures is essential reading for practising civil, structural and mechanical engineers, and graduate students of wind engineering, presenting the principles of wind engineering and providing guidance on the successful design of structures for wind loading by gales, hurricanes, typhoons, thunderstorm downdrafts and tornados.
