3.3.8.
Units and Formats
Lets you configure the units (SI and/or Imperial) and formats of variables used throughout
the program (number of decimals used for displaying or exponential format). You can use
predefined sets as the SI set, or create and save your own custom sets.
3.3.9.
Gravitation
Lets you set the gravitational acceleration constant and the
direction of gravitation as one of the global coordinate directions
or a custom direction.
If Custom direction is selected the X, Y, Z components of the
direction vector in the global coordinate system must be
specified.
If Save as default setting is checked any new model will start with
the entered value of gravitational acceleration.
3.3.10. Stiffness reduction
Seismic analysis based on
response spectrum analysis
according to Eurocode allows
using stiffness reduction factors
(k) based on architectural
element types (columns, beams,
walls, slabs, other elements) (k).
Setting stiffness reduction factors
in itself does not change the
static or dynamic results.
