C-Beam Tables - Cellular

A table of SteelFab, Inc. cellular C-Beam™, called RAMSMI.CEL, is provided with the program. Although you can create and edit tables manually, it is not recommended that you modify the RAMSMI.CEL table unless directed by the manufacturer, SteelFab, Inc.. Use spaces, not tabs, between data items. The file name must have the extension .CEL.

CAUTION: Do not use a word processor as it might embed control characters into the file.

Note: The format for the cellular C-Beam™ is different from that of the castellated C-Beam.

The file has the following format:

The first line contains an E or S, indicating English or SI units.

The C-Beam sections are then listed in the following format:

Label TopSize BotSize Dostandard flag

where:

Label

the designation for the cellular C-Beam (e.g., LB18x14).

TopSize

the label of the wide-flange section used for the top (e.g.,W12 X14).

BotSize

the label of the wide-flange section used for the bottom (e.g., W12X16).

Dostandard

the standard (ideal) hole diameter Do to be considered.

flag

a single character used to indicate whether the member is to be considered for composite or noncomposite design:

" - " means consider for noncomposite only,
" * " means consider for composite only,
" + " means consider for composite or noncomposite, and
" / " means do not use (this is used to remove a size from consideration without actually deleting it from the table).

Each label must be unique (the same label can't appear twice in the table) and it is limited to a maximum of 15 characters.

The sections must be listed in order of cost, least expensive first (generally the lightest). RAM Steel Beam Design selects the first member in the table that satisfies all design requirements and constraints.

The following is a sample listing from the RAMSMI.CEL file:
