Action
|
Code of the selected Action. It is possible to switch to another action without leaving and re-entering the input function. |
Action will be skipped (Option)
|
The action will be skipped in the calculation process if the option is selected. |
|
Number of the seismic event for evaluating the
structural response.
|
"New" option allows a quick creation of new Earthquake load.
|
|
The calculation can be done for all or only for
active elements.
|
|
Name of RM-Set (see properties) that specifies the
modes to be considered in superposition. If no RM-Set is specified, all modes
will be superposed. Content of RM-Set are series of mode numbers e.g.:
MODE 2 10 1
(Modes 2, … , 10 will be superposed)
|
|
Name of the table (variable) describing the
relationship between the no. or frequency of the considered mode and the
effective modal damping ratio.
|
|
-
Mode: the effective damping ratio
depends on the no. of the considered mode
-
Frequency: the effective damping ratio
depends on the natural frequency (in this case, the variable can also be an
expression)
-
Elements: the damping ratio depends on
structural parts (definition of the damping ratios in the element table).
Dependent on the participation of the different structural part in the natural
mode, a relevant damping for this mode is calculated.
Note: Input-3 is
optional and related to the case, that different response spectra shall be used
for different effective damping ratios. The different response spectra are in
this case assigned to the respective seismic event, together with the
corresponding damping ratio. The program evaluates the damping table and
calculates the relevant damping ratio for the considered mode. The actual
spectral value is calculated by interpolating between the spectral values of
the defined response spectra.
|
|
Lower bound for modal damping ratio [0,1]. It is
applicable only with a given damping table.
|
|
The name of the superposition file, where the
results shall be stored. Must be initialized before (action SupInit)
|
List File
|
Name of list file, where the data of the response
calculation will be listed. If the default '*' is accepted, the name of the
file will be automatically generated. eg. "resps0001" + ".lst" =
resps0001.lst for seismic no.1.
If the field remains empty, no list file will be
created
|
Delta-T
|
Duration of the Action (not applicable for this action) |
