Adding Covered Porch

[Cal]

I have a 16' wide cabin built on a slab with a 1' thick perimeter and want to add an 8' covered porch.

Does a PT 2x8 w/bolts epoxied to the slab sound sufficient to hold 2x6 joists 12" oc?  This may be on John's plan but that is in Maine and I am in Texas.

Any suggestions for bolt size and spacing?  I will be putting concrete posts and a cross beam under the other end of the joists.

Thanks,
Cal

It might work, but I would make the porch basically self supporting by putting another beam or other support under the house end as well.  I would still use a PT w/bolts epoxied to the slab to tie it all together.

I think you are on the right track w/ the 2x8 PT ledger. Do a couple of bolts every 3' or so.

Dan's suggestion is not a bad idea either as then both ends of the porch are supported in the same manner. Often the outside end supports on a porch are not as carefully done and they settle faster than the house leading to porches slanting away from the house.
