Section Modulus Calculation in Central Coordinate System

[Anonymous]

Hi All,

I'm looking at calculating the section properties of a odd shaped profile, however when I run the results of the section definition it automatically defines the principal axis off at an angle relative to the approtioned mass of the section. Whilst i can get the Iy & Iz values for the central coordinate system (see attached printout) it doesn't calculate the section modulii; is there any way to do this in Robot without having to resort to manual calculation?

Thanks in advance.

They are calculated as they are displayed on this window.

Keep in mind that robot uses data from Pricipal axes results.

Rafal,

Thanks for your reply, however I think you may have mis-interpreted what I am after. I am looking for a means of getting the values for the Elastic Section Modulus (and possibly even the Plastic Section Modulus) relative to the Central coordinate system, not the Principle Coordinate system which is oriented in the wrong direction.

The results in the attached only appear to give the Moments of Inertia for the Central Coordinate system (unless i am missing something?)

No you are not. There are no such results for Central Coordinate system - this is what I meant previously.

Sorry for confusing you.
