zeroLenght element orientation

[sisa]

Hi!
I have some problems with the zeroLenght element..I'm analyzing a simple portale frame and I would add 2 ZeroLenght element up the column in order to simulate the shear failure. I specified the orientation of ZeroLenght element bacause I want the x axis up (as one of the column)...is it right? I've assigned a shear-displacement for the elemen with an hysteretic material.
this is part of my code...When I run it, It doesn't give me error but there is a "funny" problem that it doesn't "puts" out what there is after the definition of the zero element. Also it dosen't work when I make Pushover analyzize (I run it from another code). I think the problem is the orientation of element but I dont' understand because this isn't very clear to me again. Someone could know what is the problem? I hope so! thank you

You have misspelled the command for a zeroLengthSection element.

hi dear vesna
i want to define zerolength element . how can i determine the orient of element.
we have stifness in 1 , 2 ,3 directions
thanx

Orientation of the element is defined by the following arguments: -orient $x1 $x2 $x3 $yp1 $yp2 $yp3

In the command manual you will find their meaning (http://opensees.berkeley.edu/wiki/index ... th_Element)
