Re: Bouc-Wen Material

Hi
just the script for testing uniaxial materials with a single DOF truss which you have posted, doesn't work. the force out put of truss element is zero. do you have any other script in this regard.
Many thanks.

yp vector!!

hi all.
i found that in zerolength element orientation we should use cosx sin x 0 -cosx sinx 0 respectively.
but now i have found some examples which consider zerolength element orientation like this:
x=0 degree
-orient 1 0 0 7 -1 0
x=54.83 degree
o-orient 0.576 0.817 0 4.88 1.45 0
as you can see the first three numbers are cosx sin x 0 , but what about the second three numbers which are vector components in global coordinates defining vector yp??
in this example axes 1 of zerolength element is aligned to positive Z axes.
it is so important for me. whould you please answer me as soon as possible.
thanks alot.

Zerolength element, orientation

Hello all.
I have to model a wall that its local axis are not aligned to the global axes.
How can i use orient in zero length element. Is there any example which can help me.
Also i have problem with assigning local axes of columns. I have to model columns with orientaion angle with respect to global axes.
Thanks alot.
