3/4" thick glass balaster design
3/4" thick glass balaster design
(OP)
When we design cantilevered fully temperated, glass railing (3'-6" high), the baluster is typically 4'-0" wide. Applying a 200# point load at one corner, we assume a 30 degree angle for load distribution. This allows a 2'-0" width of glass at the bottom to resist the horizontal 200# load.
What do other Engineers do?
Our client does not want to use 3/4" thick glass but our calculations indicate that the 1/2" thick glass will not work.
We are using a FS of 4 and Fy=24 ksi.

The properties of tempered glass are variable depending on the tempering process. 24 ksi is not a yield stress...it is an ultimate stress according to several references.
I would not use an all glass baluster without doing a lot more research. Maybe steel or aluminum frame with glass suspended between.

If so then this would spread the load between 2 edges.
