Comprehensive and Detailed Explanation From Exact Extract:
As building height increases, wind pressures acting on the building surfaces increase because wind
speed generally increases with elevation due to reduced friction from ground features (A).
Additionally, taller buildings experience larger lateral displacements (drift), requiring more complex
structural systems and stiffer frames to control excessive drift for occupant comfort and structural
safety (E). This requirement significantly increases structural costs.
Dead load (B) and live load (D) increase with stories but do not increase exponentially or primarily
affect wind resistance costs.
Snow and rain loads (C) mostly affect the roof, not height-related wind loads.
Choice of cladding materials (F) impacts cost but is not a primary reason for exponential wind
resistance cost increases.
