Hi folks. i got a rear porch (about 15 x 30) which is open on 2 sides. there are 3 square, steel posts along the 30 foot run holding up the roof. note: this is part of the main roof of the house, not a porch roof. i live in florida and i'm concerned about hurricane winds.
now the house was built in late 1980s and i can see steel hurricane strapping on walls and connecting rafters to top plates, etc. however, i can't see anything holding the roof down to these square posts except tiny decorative brackets.
i'm putting steel plates bolted through the posts and lagged into the wooden beam above.
however on the bottom, the only thing i can do on 2 of them is use steel "L" brackets and anchor them to the slab (porch floor).
after all that....my question: what's the best way to anchor those brackets to the floor? drill holes and set bolts in concrete? or use something like all-thread glued with epoxy?
Thanks much for any insight!
