Eigenvalues in SOFiSTiK

SOFiSTiK
1

Hello,

it is my first time performing an eigenvalue analysis of a bridge structure (plate behavior) with SOFiSTiK. Can anybody tell me if it is correct that the calculation only takes into account the self weight unless you specify to use other load cases explicitly? My code looks like this:

+prog ase urs:37.1
head Eigenwaarden structuur

ECHO OPT FULL VAL FULL

CTRL MCON 3

EIGE NEIG 6 ETYP LANC NITE - MITE - LMIN 0 LC 2001

end

Thank you in advance!

I think that the self-weight is always taken into account.

Hi, yes, I think so too. My question was rather if there are other load cases that are always taken into account without specifying them in the code, or if it is just self weight that is used unless you add other load cases that you want to take into account.
