Eurocode 1 Wind load on free-standing walls and parapets (net pressure coefficients)
Calculation of wind load action effects on free-standing walls and parapets. The net wind pressure for zones A, B, C, D along the length of the structure are calculated from the net pressure coefficients corresponding to the overall effect on the front and back faces
EN 1991-1-4:2005+A1:2010 Section 7.4.1
Supported National Annexes:
A) Calculation of pressure coefficients: Only countries that adopt CEN recommended values for section 7.4.1 of EN1991-1-4 are supported. B) Peak velocity pressure: The value of the peak velocity pressure can be specified manually. Otherwise automatic calculation of peak velocity pressure is supported, in addition to countries that adopt the CEN recommended values for NDPs, also for the following National Annexes: Finland, Portugal. The National Annexes of Germamy, Norway, Spain, Sweden, Switzerland are NOT supported (enter peak velocity pressure manually).
