In structure static analysis gravity of structure generally considered or Not

In structure static analysis gravity of  structure generally  considered or Not ?

If we won't give gravity to the structure,structure self load may acct on the body or Not?

How the structure self load acct on the body.....It depand's on gravity or any other condination

Exp...

Right nw i am doing container structure static ansys..

Cantainer structure weight apprx 500kg

External load's accting on structure  apprx 400kg

Cantainer bottom fixed.

In this case....Gravity may apply or not.

How the cantainer self load may acct on body.

I got a little confused about it.what is your view on this.
