How to make 'open -ended' stud work rigid.

[mvincentd]

Forgive the cryptic title....'open-ended' is perhaps not the best description.

 

I have 2 sections of stud work which are both only balustrade height and at one end are not captive by another wall.  I'm concerned for how to give them sufficient resistance against overturning.

 

Any ideas?

 

I'm realising as I type this a sketch might help;

We used to do handrails above stairs like this, short stud wall no strength 

we found that by increasing the size of the end stud and hiding it in the wall

you need to incorporate it in the wall like a newel post supports the end of a hand rail on a staircase 

so in effect the double thickness stud will go down below your sole plate and fix to the underlying structure

L shape bracket bolted down to block work

L shape bracket text screwed to top of rsj. 

Put extra noggins in the wall and osb on both faces to stiffen it right up.

That's broadly what I was thinking (..or all that I could think of), but was unsure it would be enough.  My SE said not to build these in blockwork as they'd be weak so i've been paranoid.

Thanks.
