D2.B.4 Built-in Steel Section Library

The following information is provided for use when the built-in standard steel tables are to be referenced for member property specification. These properties are stored in a database file are used directly for member design when these sections are specified.

Since the shear areas of the sections are built into the tables, shear deformation is always considered for these sections.

A complete listing of the sections available in the built-in steel section library may be obtained by using the tools of the graphical user interface.

Table 1. Available Australian Sections for STAAD.Pro AS 4100 Design
General Profile Type	Australian Sections	Description
I-SECTION	WB, WC	Welded beams and columns
	UB, UC	Universal beams and columns
	UBP	Univerisal bearing pile
	TFB	Tapered flange beam
T-SECTION	BT, CT	Tees cut from universal beams and columns
CHANNEL	PFC	Parallel flange channels
ANGLE	EA, UA	Equal and unequal angles
TUBE	SHS, RHS	Square and rectangular hollow sections
PIPE	CHS	Circular hollow sections

Note: STAAD.Pro will not design the following section types to AS 4100: Double Profiles (D), Composite Sections (C), Top Cover Plates (TC), Bottom Cover Plates (BC), and Top & Bottom Cover Plates (TB), Double Channels (D, BA, & FR) and Double Angles (LD & SD). Refer to TR.20 Member Property Specification for these options.

Tip: When adding and assigning sections using the built-in steel section library through the Graphical Environment, STAAD.Pro’s default tables are American. To change the default tables to Australian, select File > Configuration from the STAAD.Pro Start page (no input file open). Set the Default Profile Table to Australian on the Configure Program dialog Section Profile Table.

Refer to G.6.2 Built-In Steel Section Libraries for additional information.

D2.B.4.1 UB Shapes

20 TO 30 TABLE 'Universal Beam' ST '150 UB 14.0'
36 TO 46 TABLE 'Universal Beam' ST '180 UB 16.1'

D2.B.4.2 UC Shapes

25 TO 35 TABLE 'Universal Column' ST '100 UC 14.8
23 56 TABLE 'Universal Column' ST '310 UC 96.8

D2.B.4.3 Welded Beams

25 TO 35 TABLE 'Welded Beam' ST '700 WB 115'
25 36 TABLE 'Welded Beam' ST '1200 WB 455'

D2.B.4.4 Welded Columns

25 TO 35 TABLE 'Welded Column' ST '400 WC 144
23 56 TABLE 'Welded Column' ST '400 WC 303

D2.B.4.5 Parallel Flange Channels

1 TO 5 TABLE 'Parallel Flanged Channel' ST '75 PFC'
 6 TO 10 TABLE 'Parallel Flanged Channel' ST '380 PFC'

Back-to-back double channels, with or without a spacing between them, are are designated with the letter D in front of the section name will specify a double channel (instead of the ST designation).

15 TABLE 'Parallel Flanged Channel' D '230 PFC'
17 TABLE 'Parallel Flanged Channel' D '300 PFC' SP 0.5

In the above set of commands, member 11 is a back-to-back double channel PFC230 with no spacing in between. Member 17 is a double channel PFC300 with a spacing of 0.5 length units between the channels.

Similarly, the letters FR can be used to specify double channels front-to-front (i.e., toe-to-toe).

D2.B.4.6 Angles

Two types of specification may be used to describe a single angle. The standard angle specification may be used when the local Z axis corresponds to the z-z axis specified in G.4.2 Local Coordinate System.

16 20 TABLE 'Angle Equal' ST '30 X 30 X 6 EA'
17 TABLE 'Angle Unequal' ST '100 x 75 x 10 UA'

If the local Y axis corresponds to the z-z axis, type specification RA (reverse angle) may be used.

17 21 TABLE 'Angle Equal' RA '150 x 150 x 16 EA'

22 TO 23 TABLE 'Angle Unequal' ST '150 x 100 x 10 UA'

Note: Single angles must be specified with an RA (single angle w/reverse Y-Z Axis) in order to be designed to AS 4100. This is to ensure that the major and minor principal axes align with the local member z and y axes respectively, similar to other section profiles.

Short leg back-to-back or long leg back-to-back double angles can be specified using the SD or LD designations, respectively. In case of an equal leg angle, either SD or LD may be used.

33 35 TABLE 'Angle Unequal' SD '65 x 50 x 5 UA' SP 0.5
37 39 TABLE 'Angle Equal' SD '65 x 65 x 5 EA' SP 0.5
43 TO 47 TABLE 'Angle Unequal' LD '100 x 75 x 10 EA' SP 0.75

D2.B.4.7 Tubes (Rectangular or Square HollowSections)

Tubes can be assigned in two ways:

by catalog section - which are available in the Europe (EN 2023.db3) database
```
1 TO 5 TABLE 'SHS' ST 'SHS 20x2.5'
6 TO 10 TABLE 'RHS' ST 'RHS 100x50x3'
```
or as a parametric tube section:
```
6 TABLE ST TUBE DT 8.0 WT 6.0 TH 0.5
```
Note: No member selection is performed for parametric sections. Only code checks can be performed for parametric tube sections.

D2.B.4.8 Pipes (Circular HollowSections)

Pipes can be assigned in two ways:

by catalog section - which are available in the Europe (EN 2023.db3) database
```
1 TO 5 TABLE 'CHS' ST 'CHS 177.8x5'
```
or as a parametric pipe section:
```
1 TO 9 TA ST PIPE OD 25.0 ID 20.0
```
Note: No member selection is performed for parametric sections. Only code checks can be performed for parametric pipe sections.
