Eurocode EN 1991-1-4:2005 UK NA

Wind Load Case according to UK NA for EN 1991-1-4:2005 is implemented. Refer to the following document for further information: EN 19911-4 Eurocode 1: Actions on structures: Part 1-4: General actions – Wind actions + Annex A NA to BS EN 1991-1-4:2005

Note: The detailed procedure given in the following sections for buildings with height less than 200m. Use of wind calculation according to EN 1991-1-4:2005 for buildings taller than 200m may not be applicable.

In calculation of wind pressures, values given in the Figures NA3, NA4, NA5, NA6, NA7 and NA8 are needed. To this end, these figures are directly used in the implementation.

Basic Wind Velocity (v_b): Section 4.2

Mean Wind Velocity (v_m(z)): Section 4.3.1

Peak Velocity Pressure (q_b(z)): NA.2.17

Wind Pressure on Surface: Section 5.1

Definition of Reference Height z_e in calculation of Wind Pressure w_e

Wind Forces: Section 5.2

Structural Factor, c_sc_d: Section 6 & NA.2.20
