NMB21

2D Displacement Based Bernoulli Beam With \(N\)-\(M\) Interaction Sections

• Number of Nodes: 2
• Number of DoFs: 3 (Translation, Translation, Rotation)

Reference

1. 10.1061/JSENDH.STENG-12176

Syntax

element NMB21 (1) (2) (3) (4) [5]
# (1) int, unique element tag
# (2) int, node i
# (3) int, node j
# (4) int, section tag
# [5] bool string, nonlinear geometry switch, default: false

Remarks

Only NM2D* sections are supported. There is no validation of section attached, analysts shall make sure proper sections are used.

See SectionNM for more information about the section.

Output Type

This model supports the following additional history variables to be recorded.

variable label	physical meaning
BEAME	local element deformation
BEAMS	local element resistance

For example,

hdf5recorder (1) Element BEAME (2...)
hdf5recorder (1) Element BEAMS (2...)
# (1) int, unique recorder tag
# (2...) int, tags of elements to record

Those are local deformation and resistance (with respect to the local coordinate system) of the element.
