SPRING element in COSMOS
SPRING element in COSMOS
(OP)
Hello,
Could anyone help me? How should i use spring element in COSMOS M program?
The situation is that i need to do buckling analyse and i have a colums, which's top is fixed.
Stifness is 10500 kN/m.
Thank you!

RE: SPRING element in COSMOS
Be aware that you can have one node and two/three node springs. One node springs are good for keeping bodies from flying into space as they are basically grounded springs.
As far as you columns go, send a picture. It isn't clear what you are trying to accomplish and what part springs need to play in what you are doing.

RE: SPRING element in COSMOS
There is a situation shouwn in a picture 2, where are two columns connected with a horizontal element in the top. It would be the same, if i connected column's (lenght L) top with a spring (spring stiffnes is 10500 kN/m) that columns could only move and there will not be rotation, like it is shouwn in picture 2.
Thank you!

Interesting, because if i calculate a column, which top is not fixed, results are the same in CosmosM and MidasCivil but if the top is fixed, results are wrong.

I tried to do the same with MidasCivil program, but results were also wrong. So i found out that buckling is correct if there is only one element without spring or other construction.
