Good morning guys , on a steel frame subjected to a linear increasing load applied as a cyclic loading i applied the loading protocol shown below to get the force -displacement diagram shown on the curve down , i used a tabular data but the results doesn't match with the disered ones .  any help here ! is it the correct methode using and do i have to use some commands to get a correct curve ? 

thanks in advance .

Did you use Directional Deformation? That goes positive and negative.

Because Total Deformation is always positive.

[hamzaDZ13]

yes i used the directional deformation it's gives postive and negative values as shown above but not as the disered curve .

[peteroznewman]

I don't see any negative values in the X axis of your plot.

[hamzaDZ13]

yes exactly there is no negative values on the X axis , the displacements given on the X direction at the top of the higher comumn , so wht you think i did missing or what's your suggestions to make it correct ? do i need to specify  a deformation of  a point from the frame not all of it ? 

[peteroznewman]

In the first image, I see you have applied +/- displacement to an edge on the top right corner of the structure.

Where is the Directional Deformation scoped to?

[hamzaDZ13]

i didn't understand your last question , but  the directional deformation is set at the X axis , see in the chart controls when i put the force reaction at the X axis the curve is changed , there is a +/- values at the X axis but no on the Y axis ?

Can you send the file?

[hamzaDZ13]

how to send the ansys mechanical  files here , there is just images option ?

Instructions for sharing Workbench projects.

here i zip it on google drive , i don't know if that will help you to open it there ?
