How about using a sleeve cast
into the slab instead of a pin? The post would then slip into

Assuming the 200# is at 42", the 1"
round pin (Fy=36 ksi) won't
work. Can you use a stronger steel for the pin?

I did not check
the math on this but if 1-1/4" hollow section
works then the 1" dia round bar should have
bigger section modulus thus should also work.
To check I would treat the round bar like a

Hand rail Post -200 lbs lateral load Design
I need to check & approve a hand rail
post with 200 lbs lateral load at top.
The post is 1-1/4" square x 11 ga with 1" x
8" long insert at bottom.(4" into square
The 1" solid round bar will be placed into
1-1/2" diameter x 4" deep drilled hole in
concrete slab & filled with grout.
The 1-1/4" (ASTM A36) post works, however 1"
diameter post do not considering the round
bar will have maximum moment, just below the
Any practical way to design check this
