how to check the force at every floor

[lee7]

Hi,

If anyone knows about this. Im running time history analysis for a simple 2D steel strcuture (2-storey).

For the results i just want to know how to check the force that applied to the structure at node 112 and 113 (example for 2-storey). In post-processor it just give me total base shear.

It just easy question so if anyone could help it will be greatful.

Thanks

Hi lee,
Although I am not sure I understood completely your question, have you selected all the nodes/elements that you wish to analyse for output, in the "Analysis Output" section of the post processor? If so, you will then be able to check the 'Frame Forces' or 'Structural Displacements' in the Post Processor.
Cheers.

Hi,

You only find the total base shear because you are looking at the "Global Response Parameters".
In order to find local responses (shear, moments...), you just need to look at the "Element Action Effects" / "Frame Forces" and select the elements you are intersted in.

Cheers,
Romain

Hi,

Thanks for both of you for your help. I know the total base shear for this particular structure, but i need to know how much the force applied at every floor (force at 1st floor and force at 2nd floor with a total will give me total base shear).

I already tried what are you suggests for me but not give me the right answer.

Thanks

Hi lee.

I am still not sure if I understand exactly what you want to do. Do you want to quantify the forces at each floor to apply some assessment procedure? In this case, you'll have to quantify those forces yourself.

Or do you want to know the level of shear at each floor, caused by the seismic action? If so, you can check the shear in the columns, in the top edges, in the 'element action effects' section in the Output Results.

I hope I could help. If not, please try to explain your query better.

Hi again..

Thanks for your reply. I think i know what the problem and it my mistake. Thanks for your help.
