Elastic Section property in SAP2000

Elastic Section property in SAP2000

Elastic Section property in SAP2000

(OP)
see attached screen shots.

I'm trying to verify SAP2000 does use the Elastic section properties shown in "section properties" in its caculation for dispalcement.
I created a concrete filled pipe section, and build a cantilevered stick model using the filled pipe section, and loaded it with a simple horizontal unit dead load( not push over)
however, the displacement come out of SAP2000 is larger than if we use the beam equation; PL^3/EI. Why?

is it that I can not verify the actuall EI used in SAP2000 by using the cantilevered stick model? or SAP2000 just doesnot use the elastic properties shown in section designer( actually outside Section Designer) to calculate displacement?

Did I miss something?

Thank you all for any hint.

SAP200 takes into account the shear deformations as well, so the displacement value that is reported may be greater than yours.

So that's due different beam theories.
Thank you, John.
