BASE SHEAR RECORD

[mkfotouhi]

Hi
I asked this question before:
"How can we record the base shear?
should we use the force recorder for first story element?"
and silvia answered me:_______________
"it's better to use the node recorder with the support reactions, easier and faster."
Now my question is what is the command for node recorder to record reactions? As I see in the manual, the node recorder only use for recording ACC,VEL,DISP not for forces.
please specify for me the exact command. I need the base shear timehistory.
Thanks a lot

what version of OpenSees are you using?
or what version of the manual are you looking at?
the information about the command is in the manual:
http://opensees.berkeley.edu/OpenSees/m ... sermanual/

i recommend using the on-line manual for updates on commands.

$respType
defines response type to be recorded. The following response types are available:


disp
displacement


vel
velocity


accel
acceleration


incrDisp
incremental displacement


eigen
eigenvector


reaction
nodal reaction

I USE OPENSEES VERSION 1.6.2.d , is this version support what you mention?
thanks a lot.

yes, but you should upgrade to the latest release 1.7.0.
but the command still works.
and the manual is up to date with it.
