To create cross frame template for use with modeling
steel girder bridges, use the following procedure.
Cross frame templates make use of connection plate
templates.
-
Either:
- on the
Utilities ribbon tab, select the
Cross Frames tool in the
Libraries group
- Key in:
bmlib

-
Select the
Frame Type.
This dictates the number of members in the cross
frame.
Tip: Click
Update Drawing after each change you make to
the template in order to see these reflected in the 3D rendering.
-
For each member in the cross frame, specify the member parameters
on the
Members tab:
-
Select the
Configuration of the member:
-
Specify any vertical (along the depth of the cross frame) or
axial (along the length of the current member) offsets for both left and right
sides (looking upstation).
-
Select a
Section to use.
-
Select a
Material.
-
Select the Centerline Reference point on the member depth
(chose from Top, Middle, Bottom, or Center of Gravity of member).
-
Select the Section Rotation.
-
For Steel Tubs and Steel Girder applicable cross frames, openings can be specified
for bent plate or built-up diaphragms, by checking the option and specifying the
width, height and corner radius.
-
For each connection plate used in the cross frame configuration,
specify the plate parameters on the
Connection Plates tab:
Tip: The
plate types are arranged in a general formation of how they are arranged in a
physical cross frame
.
-
Select the connection plate
Template name.
-
Type a
Horizontal Offset and
Vertical Offset as needed.
-
For X Frames, for the Center Connection Plate you can chose
to orient it along the left or right diagonal member.
-
Repeat steps 2 through 7 to add additional cross frame templates
as needed.
-
Click
Save.
