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

  1. For structural problems, MID may reference only a MAT1 material entry. For heat transfer problems, MID may reference only a MAT4 material entry.
  2. 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.
  3. 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.
