Then click OK three times to close windows
Now we define the Layout
Next step will defining deck section
�Go to bridge
�Deck section
�Add new deck section
�Choose steel and concrete deck section ( Steel girder)
Now we have default section
we need to change girder section which is FSEC1
Assoc. Prof. Dr. Yavuz YARDIM
Assoc. Prof. Dr. Yavuz YARDIM
We need to change girder section which is
FSEC1
Go to frame section ( previous slight )
Import new section
Select wide section
From the file we select “ AISC3.pro”
Select w36x230
Click ok
Select girder as w36x230
Change number of girder to the 4
Change total width to 36 ft.
Click ok ( check next slight)
Here section is up to us W 36x230 is given that
is why we select that
If it is not given we can select a range of
available section and program will find
optimum itself .
