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.

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.

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

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.

The book follows the life of the author from his early recollections of growing up on the farm through his college training and his career as a civil engineer. It explores what forces and influences led him to desire to become an engineer, specifically a civil engineer. It shows his successes and his deficiencies and how he overcame them. His experiences directly affected the way he treated others and how he turned failures into successes. It also introduces the novice reader to the world of engineering and adds insight to the world of the experienced engineer. Even experienced engineers and highly technical trained people can always learn more from others. The book follows his career through the initial graduation of the engineer, his first summer job as a practicing engineer, and each successive career change and modification. It develops the author as he learns to deal with supervision and being in charge as well as lessons he learns as his career progresses. As his career continues to develop, he learns that he does not utilize his technical skills as much since he has other competent people working for him to perform those tasks. As a supervisor of a large group, he has to develop people skills in order to handle the problems of his group. The book finally covers the many different tasks and assignments that are required that he must handle. The author performs many tasks that are not specifically a part of his job description, but he has learned to cope with unsuspecting requests and learns to adapt. A large part of his duties involves training and teaching those who work for him to accept new challenges and pass the knowledge learned on to others. The book will give insight into the working career of an engineer and provide instruction and knowledge to the young inexperienced engineer as well as to the experienced engineer.
