After a modeled structure is defined with applied loads,
00:07
you can run several different analysis types on the structure.
00:12
In this example, a linear static analysis will be run
00:17
with the model open from the text menu, select analysis calculations,
00:23
the calculations, dialogue displays
00:26
and immediately begins loading the analysis
00:29
after a brief moment.
00:31
If no warnings or errors occur,
00:33
the dialogue closes,
00:36
be aware that the analysis is still possible
00:39
if warnings occur
00:41
but it is not possible if errors occur.
00:44
Once the analysis is complete
00:47
a notice that results fem
00:50
available
00:51
appear both at the top and bottom of the program.
00:55
Each load case combination
00:58
will now have computed stresses and strains
01:01
based on generalized section forces
01:04
to inspect the results
01:06
from the toolbar,
01:08

After a steel structure has been defined and verified,
00:07
it's time to optimize the steel members
00:11
to begin.
00:12
The structure needs to have defined groups
00:15
based on function
00:16
loads applied
00:18
and expected material effort
00:20
to define a group
00:22
from the text menu, select design
00:25
steel members design options,
00:28
members, group's definition.
00:31
This displays the definitions, dialogue,
00:35
open the groups tab
00:37
next to number. Click new,
00:41
clear the member list, text field
00:44
and in the drawing area,
00:45
select a main column,
00:48
right, click and click, select similar,
00:51
select by member type.
00:54
Click in the member list field to update
00:56
the field with the number for the main columns
00:60
in the name field.
01:01
Enter main columns.
01:05
Next
01:06
click sections,
01:08
the selection of sections, dialogue displays
01:12
under databases, select the appropriate database
01:16
and then under section families
01:19
select UC universal columns.
01:22
Click OK to close the dialogue
01:25
in the definitions. Dialogue, click save
01:29
this process repeats
01:31
for each group of members.
01:33
The groups defined after the main column
01:36
are gable wall columns, rafters,
01:39
pearls,
01:41
wal girts and braces
01:44
for each group.
01:45
Click new to create a new group.
01:48
Clear the member list field,
01:50
select the necessary components
01:53
by using selection by member type
01:56
and click sections
01:58
to define this section, databases and families.
02:02
The order in which the groups are defined makes it possible for the following group
02:07
to inherit the definitions of the preceding group.
02:10
When applicable.
02:11
For example,
02:13
since gable wall columns
02:15
use the same section types,
02:18
you do not need to assign the selection of sections
02:22
for rafters.
02:23
The selection families are different

Select the
03:01
pins using the selection by member type

select the braces and name the group
03:40
click sections to open the selection of sections. Dialogue
03:44
from here,
