PLASTIC M2

16.15

PLASTIC M2: Deﬁne the second plastic bending moment behavior for frame

elements.

This option can be used only in conjunction with the

FRAME SECTION option and is availa ble only for

FRAME3D elements. It describes the bending moment in a frame element as a function of the plastic rotation

about the second cross-section direction.

Product: ABAQUS/Standard

Type: Model data

Level: Part, Part instance

References:

There are no parameters associated with this option.

Data lines to deﬁne the variation of yield moment M

with plastic rotation:

First line:

1. Bending yield moment about the second cross-section direction.

2. Plastic rotation about the second cross-section dir ection.

Repeat this data line as often as necessary to deﬁne the relationship between the bending moment and

the plastic rotation about the second cross-section axis. At least three pairs of data are required.
