UserDefined

Create a UserDefined beamIntegration object. This option allows the user to specified locations and weights of the integration points.

beamIntegration 'UserDefined' tag N secTags locs wts

Example:

The following examples demonstrate the command in Tcl and Python script to add a Lobatto beam integration with tag 2 and 6 integration points that uses the previously defined section whose tag is 1.

  1. Tcl Code

locs = [0.1, 0.3, 0.5, 0.7, 0.9]
wts = [0.2, 0.15, 0.3, 0.15, 0.2]
secs = [1, 2, 2, 2, 1]
beamIntegration 'UserDefined' 1 5  secs  locs wtsa

  1. Python Code

locs = [0.1, 0.3, 0.5, 0.7, 0.9]
wts = [0.2, 0.15, 0.3, 0.15, 0.2]
secs = [1, 2, 2, 2, 1]
beamIntegration('UserDefined',1,len(secs),*secs,*locs,*wts)
