New Section definition

Anonymous — Tue, 08 Mar 2016 15:20:35 GMT

Good afternoon,

I have defined a new section using the 'Section Definition' tool.

However when i define as a bar in the 3D model space, the member is orientated correctly, however local axis is different. Therefore when I am investigating vertical beam bendings for these beams and others, I nee to switch between Mz and My axis.

As always, any tips welcome!

By default Robot saving a user section to the user database assumes that Y is the strong axes (IY > IZ) regardless of way (orientation) you draw it in the Section Builder module.

Thanks Artur for your reply,

So in short, just need to toggle Mz and My?

Cheers

Hi Artur,

I am trying to rotate the local bar axis around 'x' axis, so that local 'z' axis is point up so that is consistent with other members.

Thanks!

My understanding is that you want to "rotate" axes without rotating the bar itself. This would require the option that allow you to save a user section to inn the user section database in such coordinate system rater than the one "imposed" by Robot. Currently this is not possible and the corresponding request is on the wish list for the next versions of RSA.
