PBARL

PBARL – Simple Beam Property

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. No default (Integer > 0)
TYPE	Cross-section type. No default (Character: "BAR", "BOX", "BOX1", "CHAN", " CHAN1", " CHAN2", "CROSS", "H", "HAT", "I", "I1", "ROD", "T", "T1", "T2", "TUBE", "Z")
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)

For structural problems, PBARL entries may reference only MAT1 material entries.
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.
