Book Description
Excerpt from Probabilistic Estimates of Design Load Factors for Wind-Sensitive Structures Using the "Peaks Over Threshold" Approach The nominal design wind load is an extreme load with a specified probability of being exceeded during a specified time interval. For codes and standards in the United States, this interval is usually 50 years, and the specified load is based upon a 50-year nominal design wind speed. For example, for the inland Miami, Florida area, the asce Standard 7-93 [1] and 7-95 [2] specify a nominal 50-year load based on a nominal 50-year design wind speed of m s (110 mi h). It is expected, however, that a structure or element thereof should withstand wind loads substantially in excess of the 50-year Wind load without loss of integrity. The wind load beyond which loss of integrity can be expected is referred to as the ultimate wind load. The ultimate strength provided for in the design of a structure is based upon an assumed nominal ultimate wind load equal to the nominal design wind load times a wind load factor.

Book Description
The "peaks over threshold" method is used to estimate ratios of wind-induced loads with various long mean recurrence intervals to loads with a 50-year mean recurrence interval. The results support the conclusion that the load factor value of 1.3 specified in the ASCE Standards 7-93 and 7-95 is adequate for extratropical storm regions. However, for hurricane-prone regions, the results imply that the standard value of the load factor (even after being augmented by an importance factor specified in the standards) leads to nominal ultimate wind loads with considerably shorter mean recurrence intervals than is the case for extratropical regions. This suggests that the 1.3 load factor value specified in the ASCE Standards 7-93 and 7-95 is inadequate for wind-sensitive structures in hurricane-prone regions.

Book Description
The brand-new edition—with complete, up-to-date coverage of new methods and standards for the construction of wind-resistant structures Long recognized as the sole source of detailed information on the design of wind-resistant structures, Wind Effects on Structures equips designers and engineers with crucial knowledge concerning the atmosphere, the forces placed on a structure by the wind environment, and the behavior of structures under the action of these forces. Revised, updated, and augmented with material on new building codes, engineering practices, and technology, this latest edition is the most comprehensive and up-to-the-minute reference available on this important subject. New features include: Special material on the design of low-rise buildings, including building code provisions for wind loads on these structures Technical information on hurricane micrometeorology, computational fluid dynamics, empirical aerolastic models, and many other areas Easy-to-use software package for the automatic calculation of wind loads in accordance with ASCE Standard 7-95, and much more The damage done by recent hurricanes such as Andrew and Iniki has inspired a number of significant developments in the wind engineering field, from increased use of technology to predict structural loading to the creation of more stringent building codes. Long recognized as the sole source of detailed information on the design of wind-resistant structures, Wind Effects on Structures has now been fully revised to address these important changes—providing engineers with completely up-to-date methods and standards for the construction of wind-resistant structures. Divided into sections on the atmosphere, wind loads, and their effects on structures, the text now incorporates the latest information on the design of low-rise buildings, revised building code standards, and suspended-span structures, plus new material on an extensive range of technical subjects—including across-wind and torsional effects on tall structures, damping of flexible buildings, and progress in wind tunnel modeling. Combining fundamental concepts with real-world applications, this new edition features an easy-to-use software package that enables fast and accurate calculation of wind loads in line with ASCE Standard 7-95 provisions. Thoroughly updated, revised, and amended, Wind Effects on Structures provides the invaluable guidance designers and engineers need to assure the adequate structural safety and serviceability of virtually any wind-sensitive project.

Book Description
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.
