00:03
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
02:26
to clear sections
02:28
from the selection of sections. Dialogue,
02:32
click delete all,
02:34
then
02:35
select the section families, UB universal beams
02:40
and RSJ
02:42
rolled steel joints
02:44
again,
02:45
click OK to close the dialogue
02:48
and
02:49
from the definitions, dialogue, click save
02:52
pearls
02:53
inherit the same section families as rafters.
02:57
Therefore,
02:58
they do not need modification.
03:00
Select the
03:01
pins using the selection by member type
03:05
and assign the group a name
03:07
Walts
03:09
need to be assigned different section families
03:13
once selected and named
03:15
click sections
03:17
to open the selection of sections, dialogue,
03:20
clear inherited sections
03:23
and then
03:24
set the section family to RSC rolled steel channels.
03:32
Finally
03:33
select the braces and name the group
03:40
click sections to open the selection of sections. Dialogue
03:44
from here,
03:46
clear the inherited sections
03:48
and then
03:49
assign the braces to the user database
03:53
and the pr section family.
03:56
Remember to click save after each new group is defined
04:01
as new groups are made.
04:03
The group number updates automatically
04:06
once all groups are defined
04:08
close the dialogue
04:11
to begin optimization
04:13
from the text menu,
04:15
select design
04:17
steel member design options, calculation.
04:21
This displays the calculations, dialogue
04:25
under verification options, select code group design,
04:30
check optimization
04:32
and check uls limit state
04:35
next to optimization select options.
04:39
This displays the optimization options, dialogue,
04:43
adjust the options if necessary.
04:45
Click OK to close the dialogue
04:49
to modify advanced parameters, click configuration,
04:54
this displays the configuration dialogue,
04:57
close the dialogue
04:59
back in the calculations, dialogue
05:01
uncheck save calculation results
05:05
under limit states.
05:07
Select list to view the load case selection dialogue
05:12
here you can modify the ULS components
05:15
close the dialogue.
05:18
After modifications are made, click calculations,
05:22
the code group design dialogue displays
05:25
and calculations load for a few moments,
05:29
inspect the messages that appear before proceeding
05:33
open the results tab
05:35
results are displayed in groups
05:38
for each group member.
05:39
An optimal section is indicated with a blue icon.
05:44
Select change all to optimize all groups
05:48
close the dialogue.
05:51
Remember to rerun calculations after changing sections
05:55
to do this from the text menu,
05:58
select analysis calculations,
06:02
the calculations, dialogue displays
06:04
and takes a few moments to load
06:07
back in the code group calculations, dialogue, click calculations once more
06:12
to run those calculations again
06:16
again. From the code group design dialogue,
06:19
click change all to optimize sections.
06:23
Repeat this loop of calculation
06:26
until you have a stable solution. In each group.
06:30
A stable solution is indicated when two
06:32
consecutive rounds have the same optimization sections
06:36
are signed in groups.
06:38
Next
06:39
verify the SLS limit state,
06:42
select SLS from the calculations, dialogue
06:45
and then
06:46
select code group verification,
06:50
select calculations,
