After defining a steel hall model,
00:06
structural members can be assigned types according to building codes.
00:11
Please note that in this example,
00:14
the job preferences have been set to UK EC three
00:19
first assign a member type to the rafters of the structure
00:23
from the text menu,
00:25
select design
00:27
steel members design options, code parameters.
00:32
The member type dialogue displays from here,
00:35
select a new steel member type definition.
00:39
This displays the member definition parameters, dialogue
00:43
in the member type field,
00:45
enter the name rafter.
00:48
Next
00:50
select the buckling length coefficient Y icon
00:54
from the buckling diagrams. Dialogue
00:57
select ignore to toggle off buckling verification
01:02
and then click OK.
01:05
Repeat this step to toggle off the buckling verification
01:09
for buckling length coefficient Z
01:12
in the lateral buckling parameters group
01:15
check lateral buckling.
01:18
Next
01:19
select the load level icon,
01:22
