This paper presents the analysis of the modal correlation coefficient and the weighting factor for predicting wind load combination in tall buildings under wind loads by high-frequency force balance (HFFB) and high-frequency pressure integration (HFPI) in a wind tunnel. The results of the analysis and comparisons in terms of non-dimensional aerodynamic coefficients and base moments will be presented in this study, to determine whether the pressure tap on the model surface for the HFPI test is sufficiently dense. Results show good agreement between HFFB and HFPI for overall wind loads, modal correlation coefficients and weighting factors. Wind load combinations are revisited in the framework of modeling the resultant base moments in each direction. According to the findings, the across-wind load combination by weighting factor is higher than the across-wind load combination by AIJ 2004 standard for the along-wind maximum case for buildings with an aspect ratio of 1.0. In other cases, the combination of wind loads as determined by AIJ 2004 is greater than the combination of wind loads determined by the weighting factor.

Expert coverage of ASCE 7-16–compliant, wind-resistant engineering methods for safer, sounder low-rise and standard multi-story buildings Using the hands-on information contained in this comprehensive engineering guide you will be able to design and construct safer buildings that will better withstand extreme wind forces. Written by a recognized structural design expert, the book explains the general concepts and principles involved in the design of buildings and structures for wind forces. Structural systems used to resist wind forces are outlined and explained, in the context of both low-rise and high-rise buildings. Building Design for Wind Forces provides easy-to-follow summaries of complex ASCE 7-16 wind load provisions and shows how to apply the corresponding design procedures using practical examples. A detailed discussion of typical structural damage caused by extreme wind events such as hurricanes and tornadoes is presented along with design recommendations. Current wind engineering activities and recent research developments are discussed, and a general overview of wind tunnel procedures and an introduction to the concept of database-assisted design (DAD) is provided. Building Design for Wind Forces covers: • Wind forces and wind effects on buildings and structures • Wind load provisions of the ASCE 7-16 standard • Damage to structures caused by extreme wind events • Wind engineering activities and research trends • Structural systems for lateral loads • Tall buildings • Wind design procedures and wind load parameters • Wind loads on the Main Wind Force Resisting System (MWFRS) • Wind loads on Components and Cladding (C&C) • Wind loads on building appurtenances and other structures • Wind tunnels and the wind tunnel procedure • Database-assisted design (DAD)

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 first of its kind, Designing Tall Buildings is an accessible reference that guides you through the fundamental principles of designing high-rises. Each chapter focuses on one theme central to tall-building design, giving you a comprehensive overview of the related architecture and structural engineering concepts. Mark P. Sarkisian provides clear definitions of technical terms and introduces important equations, to help you gradually develop your knowledge. Later chapters allow you to explore more complex applications, such as biomimicry. Projects drawn from Skidmore, Owings and Merrill’s vast catalog of built high-rises, many of which Sarkisian designed, 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.
