Problem with Gravity Analysis of homepage example

Post by JaCl »

Hi,

I did the example of your homepage: >>Pushover Analysis of 2-Story Moment Frame<< (http://opensees.berkeley.edu/wiki/index ... ment_Frame) and it seems to work quite well.
But now I inserted a node recorder to record the nodal reaction of the 3 nodes at the base (numbers 11, 21, 31) for the GRAVITY ANALYSIS.
If I look at the results, I just get values for the 3rd node (that of the PDelta-column, number 31), but the other two nodes show zero (although the Forces on the nodes of the frame aren't zero!)

Since I have the same problem in an more complicated model, I wanted to ask, whether anyone knows where the problem is. It seems to me that the model (from the above mentioned 2-Story Frame) is fine,
also the recorder works good. Has anybody an idea, where the mistake is?

Thanks a lot for any comment, hint or help

Clemens

What I have forgotten: the redorder I added looks like this

set recorderCommandGravity "recorder Node -file Gravity.txt -time -node 11 21 31 -dof 2 reaction"
set rectagGravity [eval $recorderCommandGravity]

and after the analysis:
remove recorder $rectagGravity

thanks, Clemens
