can't get any result!!

[kadirtopcu]

I modeled a simple frame with braces, then I applied a lateral force. I want to get section local forces record but after running there was nothing on the braces.no moment, no axial load ..nothing?? what could be the reason of this problem?

[fmk]

check the nodal displacements at the ends of the brace elements to make sure they are not 0.'s

Without further details, I'd say you're trying to record something that's not being computed.

the frame is like this. imagine a 5x5 2D frame:

node 1 0 0
node 2 0 5
node 3 5 5
node 4 5 0
node 5 2.5 5 (in the middle of 2 and 3)

element 1 1 2
element 2 2 3
element 3 4 3
element 4 1 5
element 5 4 5

element 4 and 5 are braces. after running the program there was nothing on the braces. no axial loads no momentswhat could be the reason.
and also if I define braces like this:
element 4 1 3
element 5 4 2

it works and I can get axial loads and moments on the braces...what is the difference???
I hope I can express it clearly..thanks

You are not getting any results because your braces are not connected to the top chord, you have two zero force members. Instead of one element from node 2 to 3, you should try an element from node 2 to 5, and node 5 to 3. If you do that your braces will no longer be zero force members.

I did what you say, but it doesnt work.Do I miss something here? please help because I need to solve this problem..

[TJC]

Post your complete input script, without that it's difficult to solve your problem.

thank you TJC, I have done what you say again and it works now.
