Preface to the Fourth Edition of Wind Effects on Structures: Modern Structural Design PDF:
The quarter of a century that elapsed since the publication of the third edition of Wind Effects on Structures has seen a number of significant developments in micrometeorology, extreme wind climatology, aerodynamic pressure measurement technology, uncertainty quantification, the optimal integration of wind and structural engineering tasks, and the use of “big data” for determining and combining effectively multiple directionality-dependent time series of wind effects of interest. Also, following a 2004 landmark report by Skidmore Owings and Merrill LLP on large differences between independent estimates of wind effects on the World Trade Center towers, it has increasingly been recognized that transparency and traceability are essential to the credibility of structural designs for wind. A main objective of the fourth edition of Wind Effects on Structures is to reflect these developments and their consequences from a design viewpoint. Progress in the developing Computational Wind Engineering field is also reflected in the book.
Modern pressure measurements by scanners, and the recording and use of aerodynamic pressure time series, have brought about a significant shift in the division of tasks between wind and structural engineers. In particular, the practice of splitting the dynamic analysis task between wind and structural engineers has become obsolete; performing dynamic analyses is henceforth a task assigned exclusively to the structural engineering analyst, as has long been the case in seismic design. This eliminates the unwieldy, time-consuming back-and-forth between wind and structural engineers, which typically discourages the beneficial practice of iterative design.
The book provides the full details of the wind and structural engineers’ tasks in the design process, and up-to-date, user-friendly software developed for practical use in structural design offices. In addition, new material in the book concerns the determination of wind load factors, or of design mean recurrence intervals of wind effects, determined by accounting for wind directionality.
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
