PBARL

Bulk Data Entry Defines the properties of a simple beam (bar) by cross-sectional dimensions, which is used to create bar elements via the CBAR entry.

Definitions

Field	Contents	SI Unit Example
`PID`	Unique simple beam property identification. Integer Specifies an identification number for this property. <String> Specifies a user-defined string label for this property. 2 No default (Integer > 0 or <String>)
`MID`	Material identification. 1 2 Integer Specifies a material identification number. <String> Specifies a user-defined material identification string. No default (Integer > 0 or <String>)
`GROUP`	Indicates if an arbitrary beam section definition is to be used. Refer to Arbitrary Beam Section Definition in the User Guide. If the value of this field is HYPRBEAM, the following field is `NAME`; otherwise it is `TYPE`. Default = blank (blank or HYPRBEAM)
`TYPE`	Cross-section type. When `GROUP` field is blank, this field is `TYPE`. BAR BOX BOX1 CHAN CHAN1 CHAN2 CROSS H HAT I I1 ROD T T1 T2 TUBE Z HEXA No default
`NAME`	Name of arbitrary beam section definition. Refer to Arbitrary Beam Section Definition in the User Guide. When the value of `GROUP` is HYPRBEAM, this field is `NAME`. No default (Character string)
`ND`	Number of dimensions used to specify the Cross-section shape. This is required when the value of the `GROUP` field is HYPRBEAM. `ND` represents the total number of dimensions used to define an Arbitrary Beam Section. Default = blank
`DIMi`	Cross-sectional dimensions. No default (Real > 0.0)
`NSM`	Nonstructural mass per unit length. `NSM` is specified after the last `DIMi`. Default = 0.0 (Real)

Comments

For structural problems, MID may reference only a MAT1 material entry. For heat transfer problems, MID may reference only a MAT4 material entry.
String based labels allow for easier visual identification of properties, including when being referenced by other cards. (For example, the PID field of elements). For more details, refer to String Label Based Input File in the Bulk Data Input File.

The cross-sectional properties, shear flexibility factors, and stress recovery points (C, D, E, and F) are computed using the TYPE and DIMi as shown below. The origin of the element coordinate system is centered at the shear center of the cross-section oriented as shown. The PBARL does not account for offsets between the neutral axis and the shear center. Therefore, the CHAN cross-sections may produce incorrect results. The PBEAML entry is recommended.

The torsional coefficient (J) is approximate for non-regular hexagons (TYPE = HEXA).
