PBARL – Simple Beam Property
Description
Defines the properties of a simple beam (bar) by cross-sectional dimensions, which is used to create bar elements via the CBAR entry.

Field |
Contents |
PID |
Unique simple beam property identification number. No default (Integer > 0) |
MID |
Material identification number. See comment 1. No default (Integer > 0) |
GROUP |
Indicates if an arbitrary beam section definition is to be used. Refer to Arbitrary Beam Section Definition in the User’s 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. No default (BAR, BOX, BOX1, CHAN, CHAN1, CHAN2, CROSS, H, HAT, I, I1, ROD, T, T1, T2, TUBE, Z, or HEXA) |
NAME |
Name of arbitrary beam section definition. Refer to Arbitrary Beam Section Definition in the User’s 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) |
| 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. | 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. |
