Crane Runway Data - Beam Data
(Revised: 05/09/2016)
The Crane Runway Data - Crane Beam Data tab is used
to define the Crane Beam, Channel, and Rail for this runway location.
The
Deflections Limits and Impact Factors are defaulted based on the Building Code.
Options:
Shape
From
this drop list, select the material shape for the Beam and Channel. Selections are 3 Plate Built-up, S Shape –
Hot Rolled, S Shape with Channel, Wide Flange – Hot Rolled, and Wide Flange
with Channel. This selection will make
the following three fields activate depending upon the choice of the Beam and
Channel.
Beam Size / Web Thk
From
this drop list, select the Crane Beam Size for Hot Rolled members, and Web
Thickness for Built-up members.
Channel Size / Top Flange
From
this drop list, select the Crane Channel Size for Hot Rolled members, and Top
Flange size for Built-up members.
Bottom Flange
From
this drop list, select the Bottom Flange size for Built-up members.
Rail Size
From
this drop list, select the Crane Rail Size.
By Others
Select
this check box if the Wide Flange or Wide Flange with Channel are not being
supplied by the Steel Building Manufacturer.
When this check box is selected, the other check box saying Crane Beam Will Laterally Support Column
will automatically be unchecked.
Future Crane
Select
this check box if the frames are being designed for a crane system to be
installed at a future date. Checking
this box will automatically check the By
Others box and deactivate (un-check) the Crane Beam Will Laterally Support Column option.
Crane Beam Will Laterally Support Column
This
box is checked by default for Top Running Bridge Cranes (TRBC) but may be
un-checked if non-standard diagonal crane beam bracing is used. The column support provided by the runway
system is located at the elevation of the top of the runway beam and is
considered to fully support both flanges of the column. This function has no meaning, and is inactive
for Underhung Bridge Cranes (UHBC).
Design Crane Beam
This
button will allow you to do a preliminary design of the Crane beam.
Optimize beam-channel configuration
This
option is selected by default and allows the system to select the most optimum
beam with or without a cap channel.
Uncheck the box and select a Shape of Wide Flange with Channel or Wide
Flange – Hot Rolled as required.
The
screen below will pop up to display the resulting runway beam design
information.
Check Crane Beam
This
button will check the Crane Beam information that is input manually in the
screen, per the AISI design.
