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. |
|
Load case name
|
Name of the load case to be calculated. The load
case must contain at least two load sets, one load set with constant factor
which contains all effective masses of the structure, and one or more load sets
describing the actual time dependent loading. This load-set must have assigned
a variable factor describing the variation of the loads of the load set with
time. The variable load factor must have been defined in Properties >
Variables as formula or table covering the whole investigated time period.
|
|
Output Type
|
The program allows for creating an envelope of
max/min values of all result parameters (deformations and internal forces)
and/or a video of the dynamic behavior of the structure. The output type can
have the following settings:
-
ENV (or empty): Default. Only the
envelope of result components is created.
-
VIDEO: Only the video showing the
dynamic behavior is created.
-
ENV+VIDEO: The envelope as well as the
video are created.
|
|
Delta-t
|
Investigated time period in seconds. Note that the
variable load factor(s) must be defined over the whole range and that the time
step length defined in Recalc > Dynamic essentially governs the required
calculation time. The required maximum time step length is dependent on the
relevant natural frequencies and should be not more than 0.01 sec, better 0.002
sec to achieve the required accuracy.
|
|
|
One of the pre-defined 3d-view layouts (defined in
the menu View) can be selected for the presentation of the video.
Default: DefaultLayout
|
|
|
An option for defining sub-steps in time history
analysis to accommodate adaptive sub-stepping. The default sub-steps is 10.
Desired range of sub-stepping can be entered in the form of range: (start: end:
step) e.g. 10:20:1 would mean that a given problem if fails at a certain time
step to achieve equilibrium then it would be further sub-divided into 10
sub-steps and will go till 20 in the step of 1 until it finds equilibrium.
|
|
|
RmSet which is relevant for print-out and graphic
presentation of selected result parameters. The action TInt allows for writing
a list file with the full time history of selected result values and provides
on the screen a graph showing the time history of selected result values. This
screen graphics is also written to a plot file with the name
tintxxx.pl (xxx is the the load case name as defined in Input-1).
The relevant result components for writing into the detailed list file and/or
for being presented in the graph on the screen must be defined in an RmSet of
the type TINT.
Note: RM-Set type RHIST can be directly created.
|
|
|
Default: The video will be presented in
"real time", i.e. if the calculation period is 10
sec the length of the video will also be 10 sec. With the speed factor the
presentation can be made faster or slowed down.
|
|
|
Resolution of the video in pixels in horizontal and
vertical direction. In order to limit the created video files to a reasonable
size it is recommended not to chose a very high resolution.
Default: 640:480
|
|
(*.sup)
|
Name of the superposition file, where the envelope
results will be stored. The same name is used with the extension
*.AVI for any created video file.
Note: The
superposition file must be initialized with the action SupInit before the
action TInt is performed.
|
|
|
Name of the list file where the load protocol and
time history of the relevant result parameters (deformations and internal
forces as defined in the RmSet) are written.
Default (*):
tintxxx.lst with
xxx being the load case name as
specified in Input-1. No list file will be created if the input field is empty.
Excel file: Independent of specifying a
list file name, an comma separated values file in text-format
(*.csv) is automatically written with the name of the
output file specified in Output-1 and the extension
.csv (these files can be opened in most
spreadsheet programs, such as
Microsoft®
Excel®). It contains the time
history of the deformation result parameters (no internal forces) as defined
for printout in the RmSet. In addition it shows the respective deformation
velocities and accelerations. Like envelopes, the CSV file is directly written
into the project directory, not into the sub-directory of the respective
schedule variant.
Note: The presented
velocities and accelerations are the calculation values used in the Newmark
time integration scheme. For mathematical reasons these may be relaxed or
over-relaxed. Therefore, for accurate assessment, especially of acceleration
values, it is recommended to recalculate them from the displacements instead of
using these internal calculation values..
