4.12. beamIntegration commands¶

beamIntegration(type, tag, *args)¶ A wide range of numerical integration options are available in OpenSees to represent distributed plasticity or non-prismatic section details in Beam-Column Elements, i.e., across the entire element domain [0, L].
Following are beamIntegration types available in the OpenSees:
Integration Methods for Distributed Plasticity. Distributed plasticity methods permit yielding at any integration point along the element length.
- Lobatto
- Legendre
- NewtonCotes
- Radau
- Trapezoidal
- CompositeSimpson
- UserDefined
- FixedLocation
- LowOrder
- MidDistance
Plastic Hinge Integration Methods. Plastic hinge integration methods confine material yielding to regions of the element of specified length while the remainder of the element is linear elastic. A summary of plastic hinge integration methods is found in (Scott and Fenves 2006).
