Performance-based wind design for tall structures has developed slowly due to several issues including duration and directionality of wind loading, element fatigue, computational methods and other dynamic responses. This course looks at the latest innovations in PBWD and how these new designs are being implemented in the context of new building techniques.

How Famous Building Around the World Consider Wind Loads
One of the most important forces that civil engineers, architects and urban planners need to take into account in the building design process is wind. For high-rise buildings, the risk of being affected by the wind is particularly critical. This article focuses on wind loads and how professionals working in the architecture, engineering, and construction (AEC) industry can benefit from simulation to analyze the loads and safety of the built structures.

Performance-based wind design: The New Frontier
With the release of the ASCE/SEI Prestandard for Performance-Based Wind Design (PBWD) in August 2019, the industry has taken an initial step toward implementing a structural engineering technique similar to well-established Performance-Based Seismic Design (PBSD) for the other most common building environmental hazard, wind. The Prestandard outlines an alternative and comprehensive approach to building design for wind loading, which explicitly evaluates occupant comfort, building drift, and extreme wind event behavior.

Performance-based wind design: What is it and how is it implemented?
The recent publication of the ASCE/SEI Prestandard for Performance-Based Wind Design (Prestandard), and the Manual of Practice on Design and Performance of Tall Buildings for Wind prepared by an ASCE/SEI Task Committee, make this an apt time to provide an overview of the intent of these documents, the present state-of-the-art in Performance-Based Wind Design (PBWD), and current efforts to update knowledge.

Why Tall Buildings Need Wind Load Analysis
The challenges associated with the effects of wind on a structure are complex, and if not correctly assessed and considered, they can contribute to the instability of buildings. For tall buildings, average wind speed increases with height, and the gustiness, or different combinations of eddies (circular movement of wind), decreases with height. This article discusses why computational fluid dynamics simulations and calculations, in the wider context of MEP engineering design, are vital to determine the stability and safety of tall buildings.
