Forces in nodes

[Anonymous]

Hi!

Where can I find how much force (in the x-axel) each highlited node is exposed to?

Best regards,

Lina

Results >> forces .

see the attachment . is it ok ?

That's what I thought, but I can't choose "Forces" for this type of structure.. what can I do about it?

[Mohammed_Ata]

From your attachment , it seems that you defined only walls and floors which are be described as pannels .

to get forces on them ... Results >> plate  and shell results

[dimogrec]

"Forces" results are refered to bar elements. The same goes for "Deflections" and "Stresses". As Mohammed wrote it seems you have no bar elements in your model.

Does this mean that I can't get the force for one wall in my model?

[dimogrec · Accepted solution]

There are different options for that

results-> diagram for buildings -> core walls (presupposed that first you need to tansform a wall to a core)

results-> core walls (table)

results -> maps  then check membrane forcesN or M, or Q

results -> Plate and shell results (table)

Also the results in "story table" have infos about walls

Hi again..

I've found the force in each wall after transforming them into core walls, then I've got the result in the table "Definition and results for core walls". It's here shown different results,

Core Wall/Story/Cut/Case

What I understand Cut shows two values for one wall in one story, (Cut 1 and Cut 2) on the lower edge and on the upper edge. Is this correct?

My question is, how can I get the result on just one Cut?

Not sure if this is explained enough, let me know!

 Not possible.

Copy table to Excel and delete records for Cut 1 or 2

 Hi

iI continue this thread because i have a substructure to study..

Is it possible to extract the efforts in the highlighted nodes from the global model, in order to use them as simple cases.

[Simau]

Just a precision,

when these nodes are in foundation, it is posible to get the efforts via the reactions, as explained here

My question concerns the nodes of the upper levels of a building.

Ok Rafal,

I remember this thread.

It was very usefull to get forces from nodes with frame structure.

With nodes in pannels, it doesn't work.

It's difficult to modify Finite Element model by introducing riigd links at the place we need information.

So, is there a mean to get directly efforts on hilighted nodes?

If exists, this method will be great.

[Simau]

Hi,

I come again about this topic.

If we need efforts on the lower nodes of  a panel, how do we proceed?

Its possible for nodes on bars, but not on nodes panels.
