4.2.4.1. BeamColumnJoint Element¶

This command is used to construct a two-dimensional beam-column-joint element object. The element may be used with both two-dimensional and three-dimensional structures; however, load is transferred only in the plane of the element.

element('beamColumnJoint', eleTag, *eleNodes, Mat1Tag, Mat2Tag, Mat3Tag, Mat4Tag, Mat5Tag, Mat6Tag, Mat7Tag, Mat8Tag, Mat9Tag, Mat10Tag, Mat11Tag, Mat12Tag, Mat13Tag, <eleHeightFac=1.0, eleWidthFac=1.0>)

`eleTag` (int)	unique element object tag
`eleNodes` (list (int))	a list of four element nodes
`Mat1Tag` (int)	uniaxial material tag for left bar-slip spring at node 1
`Mat2Tag` (int)	uniaxial material tag for right bar-slip spring at node 1
`Mat3Tag` (int)	uniaxial material tag for interface-shear spring at node 1
`Mat4Tag` (int)	uniaxial material tag for lower bar-slip spring at node 2
`Mat5Tag` (int)	uniaxial material tag for upper bar-slip spring at node 2
`Mat6Tag` (int)	uniaxial material tag for interface-shear spring at node 2
`Mat7Tag` (int)	uniaxial material tag for left bar-slip spring at node 3
`Mat8Tag` (int)	uniaxial material tag for right bar-slip spring at node 3
`Mat9Tag` (int)	uniaxial material tag for interface-shear spring at node 3
`Mat10Tag` (int)	uniaxial material tag for lower bar-slip spring at node 4
`Mat11Tag` (int)	uniaxial material tag for upper bar-slip spring at node 4
`Mat12Tag` (int)	uniaxial material tag for interface-shear spring at node 4
`Mat13Tag` (int)	uniaxial material tag for shear-panel
`eleHeightFac` (float)	floating point value (as a ratio to the total height of the element) to be considered for determination of the distance in between the tension-compression couples (optional, default: 1.0)
`eleWidthFac` (float)	floating point value (as a ratio to the total width of the element) to be considered for determination of the distance in between the tension-compression couples (optional, default: 1.0)
