TR.19 User Steel Table Specification

STAAD.Pro allows you to create and use customized steel section tables for use in the property specification, code checking, and member selection. This set of commands may be used to create the tables and provide necessary data.

General Format

TABLE i1  (fn )

The following commands are repeated for each section within the user-table.


For General sections, the following may be specified for each section:

zp1 yp1 zp2 yp2zpn ypn )
zs1 ys1 zs2 ys2 zs3 ys3 zs4 ys4 )

All tables end with the following command:



i1 table number (1 to 99). During the analysis process, the data in each user provided table is stored in a corresponding file with an extension .U0n . For example, the data of the 5th table is stored in .U05. The first part of the input file name is the same as that of the STAAD input file. These files are located in the same working directory as the input file. Hence, they may later be used as external user provided tables for other input files.
fn external file path and file name containing the section name and corresponding properties (up to 72 characters). If an external file is used, the no other data should be provided for this table.
Note: Hyphens (i.e., dashes) may not be used to break a line within the external file path and name. This line may be up to 250 characters long.
section-type a steel section name including: WIDE FLANGE, CHANNEL, ANGLE, DOUBLE ANGLE, TEE, PIPE, TUBE, GENERAL, ISECTION, & PRISMATIC.
section-name Any user designated section name, use 1 to 36 characters observing the following rules:
  • Only alphanumeric characters and digits are allowed for defining section names (i.e., spaces, asterisks, question marks, colons, underscores, semi-colons, etc. are not permitted).
  • The first three characters of the section names in pipe and tube tables must be PIP and TUB, respectively.
  • The first the characters of the section names in all other tables cannot start with PIP or TUB.
  • A name can be duplicated in different tables, but must be unique within any individual table.
property-spec Properties for the section. The requirements are different for each section type as follows. Shear areas AY and AZ must be provided to ensure proper shear stress or shear strength calculations during design.

The default length units for properties are the current units. If a UNIT command is entered within the User Table in the input file then those units become the current units. However, a UNIT command on an external file only affects that file and has no effect on the units in subsequent input file commands. You may specify the desired length unit by using the UNIT command as the first command in the table (see example following this description).

If data is from input file, then use up to three lines of input per property-spec (end all but last with a hyphen, - ).

General Section Definitions

The commands PROFILE_POINTS and STRESS_LOCATIONS can be used with a user-table general shape only. These define the vertices of a closed shape and the four locations to calculate stress, respectively.

  • zp1 yp1 zp2 yp2zpn ypn are the X and Y pair of local coordinates which describe the points of the section. The points should be provided in either clockwise or counter-clockwise order.
  • zs1 ys1 zs2 ys2 zs3 ys3 zs4 ys4 are the X and Y pair of local coordinates which indicate where the stress is calculated. It is recommended that these start with the top,left-most point. The extreme points of the cross-section are then specified in a clockwise order around the section. Though any coordinates may be entered, points should lie on the section defined in order to represent true stress values.
Note: Hyphens (i.e., dashes) may not be used to break a line of PROFILE_POINTS or STRESS_LOCATIONS data.
CAUTION: Do not use comments (i.e., lines that start with an asterisk) within the PROFILE_POINTS and STRESS_LOCATIONS definitions, as these lines will not be ignored by the STAAD engine. This will result in unintended sections or errors.
Tip: Using the Graphical Interface is recommended for entering these points, as they may be entered with respect to any local coordinate system and will be translated to the section's center of mass and the section property-spec values will be calculated automatically. See M. To create a general section for details.
