Wind loads can be automatically generated as member loads or area loads on the following structural components (optional with internal pressure for open buildings):
Area loads can be automatically converted into member or line loads. There are 3 options available for this:
Generate Member Loads from Area Load via Plane
Member loads from area loads via cells
Line loads from surface loads on openings
In the case of member loads from area loads, a plane has to be defined via corner nodes or cells have to be selected in the graphic. The area load can either be applied to the entire surface or only the effective or projected surface of the members.
For the 'Line Loads from Area Loads on Openings' function, the corresponding openings are selected.
Area loads can be automatically converted into member loads. There are 2 options available for this:
Generate Member Loads from Area Load via Plane
Member loads from area loads via cells
Depending on the selected option, you either have to define a plane via corner nodes or select cells in the graphic. The area load can either be applied to the entire surface or only the effective or projected surface of the members.
The material library already includes Swiss types of concrete and reinforcing steel available for design. However, you can always define other materials for the design according to SIA 262. The program performs the ultimate and the serviceability limit state design.
The crack width analysis can be performed using the design of Sigmas,adm, rebar spacing sL, or a direct calculation of crack widths according to the technical documentation D0182. Depending on the selected concrete type, the program determines the limit value Sigmas,adm according to D0182, Eq. 10.13; the upper limit is set by the design criterion fsd.
The material library already includes the Chinese types of concrete and reinforcing steel available for design. However, you can always define other materials for the design according to GB 50010.
In addition, it is possible consider the seismic design according to the standard GB 50011‑2010 (Code for seismic design of buildings).

You can define platforms, tubular extensions, antenna brackets, antennas, inner ducts, cable ducts, and ladders in separate input windows. Extensive libraries including parameterized models facilitate the entry.
There is an interactive graphic available in all input windows. This way, you can immediately see the position of tower equipment.
