ElasticTimoshenkoBeam

Post by fponta »

Hi there everybody!

I was trying out this new beam element given with 2.4.3 but I can't make it work as I get the following error:
OPS_GetIntInput -- error reading 13
WARNING invalid element data (transTag) element ElasticTimoshenkoBeam3d 1
TclElementCommand -- unable to create element of type : ElasticTimoshenkoBeam
expected integer but got "-rho"

I used the following string I found in the source code as reference:
element ElasticTimoshenkoBeam3d $tag $iNode $jNode $E $G $A $Jx $Iy $Iz $Avy $Avz <-rho $rho> <-nlGeo> <-cMass>

What's wrong?
Any help appreciated.

Ok, I figured it out. The reference line should be something like:
element ElasticTimoshenkoBeam3d $tag $iNode $jNode $E $G $A $Jx $Iy $Iz $Avy $Avz $transfTag <-rho $rho> <-nlGeo> <-cMass>
the transfTag was missing.
By the way I expected to get this string by typing "element ElasticTimoshenkoBeam" but what I get is a crash. Did this behaviour change with the new version?

Out of curiosity, is the element documented? I can't find it in the element list in the command manual: http://opensees.berkeley.edu/wiki/index ... nt_Command
