Module WIND and module WND
WIND module (DIN 1055-4:1981)
For the general stability proof according to AD 2000 Merkblaetter section S3/0, the resulting forces and moments in different sectional planes must be considered.

According AD-S3/0:2007 section 4.1.4.6 wind loads can be calculated directly per DIN 1055-4 or for high and slender vessels (H>20m, H/D>10) according DIN 4133:1991. In the AD Merkblatt G2 the new edition DIN 1055-4:2005 is cited, while a design according DIN 4133:1991 is related to the former edition DIN 1055:1986. Additionally a pre-standard DIN V 4133: 2007-07 was published. New: The WND module calculates the wind loads according section 10 of the DIN 1055-4:2005 / correction 1 of not vibration sensitive buildings. Compared to edition 1986 the values of the dynamic wind pres-sure have been changed and several terrain categories have been brought into use. Different blast velocity profiles for 25m and 300m are now predefined. |

The S30 module, section wind load calculates the wind load and wind moment on a vessel with given wind velocity and aerodynamic form factor. Attachments with an additional area of not more than 15% of the vessel area may be considered globally by an increased dynamic wind pressure of 25%.
The ANBA module calculates the stress in a cylindrical apparatus with structural attachments up to 50m height considering the vibration sensitivity according DIN 4133:1991. Attachments such as ladders, platforms (segments and entire platforms), parallel tubes and catwalks can be taken into account.
The VERK module calculates the stress in a cylindrical vessel without structural attachments up to 50m height considering the vibration sensitivity according DIN 4133:1991. The wind load (wind load zone) and the snow load (snow load zone) are calculated as live loads.
