Wind actions on structures and structural elements is determined taking account of both external and internal wind pressures.
A summary of calculation procedures for the determination of wind actions is given below.

Roughness coefficient cr(z)
External pressure coefficient cpe
External wind pressure: we=qp cpe
Wind forces on structures
Structural Factor cscd
