columns for shelter / gazebo on 4" slab

I have a 13' x 13' slab, 4" deep. I want to build a shelter / gazebo. Simply 4 columns and a roof.

What is the best way to anchor the columns (4x4 wood)?

I hear I may have to break part of the slab (where the columns would go) and dig it 24". Is this the correct procedure?

I am in Fort Lauderdale, FL. Hurricane country.

Thanks,
George

Check your building code locally to see what is required.

You will have to worry about uplift and the horizontal wind force.

For lateral resistance, you must go deep in the ground and/or diagonal bracing in two directions. I would imagine your code addresses these two basic points.

Bolting to the slab won't fly. - or maybe it will make it fly (LOL).

Make it a tiki hut. It will blow away in a hurricane, but at least it won't damage your neighbors when it does so.
