Free End Wind Post
Free End Wind Post
(OP)
Hi,
I have been asked to install a wind post to restrain a free end of a masonry panel. I have a 215 inner leaf, a 180mm cavity and a 100mmm outer leaf, all blockwork.
The odd thing is the Arch wants to place the wind post on the inside of the inner leaf so I imagine the wind post will have to be bolt fixed to the inner face of the inner leaf and then tied to the structure over and at the floor level.
Has anyone done this detail before or have any issues with it. I 'm used to calling wind posts up built into the inner leaf or installed within the cavity.
John.

Meant to add a sketch of the detail, see attached.

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

Would increasing the base plate size avoid this. The moment I have 26.5kNm. The slab is 200 in total (50 screed with A142 mesh) on a 150 prestressed hollowcore slab, and the voids have been filled locally in this area.

I'm just not too sure how to convert the moment into a point load so I can get the precast supplier to check punching?
I know that Force = Moment/lever arm but is my lever arm the distance from the centre of the post to the edge of the baseplate?

The connection to the wall on the right side of your sketch is weak, if to scale. I would run a bent plate around the corner so you can bolt to the end of the block wall.

Can you run the wind beam down to the next level to give you a backspan?
