NMB21E

2D Displacement Based Bernoulli Beam With NN-MM Interaction Sections And End Moment Release

  • Number of Nodes: 2

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

Syntax

element NMB21EL (1) (2) (3) (4) [5]
element NMB21EH (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.

The NMB21EL element releases the moment at low node i and the NMB21EH element releases the moment at high node j.

A non-iterative algorithm is used.

See SectionNM for more information about the section.

Output Type

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

variable labelphysical 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.
