Section check of Castellated Beams and other questions

[sonyablade2010]

Dear All, 

1. I would like to know is it possible to cross section check the built-up sections especially castellated beams. Because in RSA2012 it is not possbile to section check the castellated beams due to the code. If there was a work around for this I kindly would like to know it.
2. What is the bracket tool for ? As a result we do have option to model the connnection as top/bottom haunch type and this also can serve as bracketing type. 
3. How to modify the node sizes in views to make them more visible, the light blue ones.

Regards,

There are several topic on the forum that describe how to code check user defined sections.

For the castellated beams the code checking in Robot is limited to Polish code onlyhttp://forums.autodesk.com/t5/Robot-Structural-Analysis/beams-with-castellated-web/m-p/3409237

This allows you to get more accurate distribution of internal forces in a model.

In order to fully benefit software features its crucually important to know its capabilities in special cases like this, Can you elaborate that topic a bit further? For example, does it modify the connecting elements stiffness matrices in that joint in order to represent rigid zone effect or something else? Based on your post I infer that its not compulsory but It'd be better for fine internal load distrubition mechanism if its used, right?

• How to set the same weld size for all connection types, it will save me a lot of time if I don't do it manually, setting for example 6mm for each editbox ?
• How to unite two elements which share the same proerties, theres is a tool for division but there is no tool to join them beack other than undo?

If you add a bracket this part of the original bar (section) is replaced with a tapered I section of size which correspond to the size of the original section and original section plus the defined bracket end properties at its ends).

Currently there is no such option available.
