ABSTRACT

For tall buildings, wind forces and pressures are often the governing factor for the design of the structural system and the strength of the building envelope, being even more dominant than the forces due to earthquakes. This chapter describes the different types of wind that nature produces, how the wind behaves aerodynamically when it meets a tall building, the forces and pressures that it exerts, and the building’s response to those forces and pressures. This chapter is focussed primarily on the mitigation of wind forces in tall buildings. Wind as a potential generator of energy is covered in Chapter 13.
