Hi XXXXX;
Any snow load?
Type of roofing material?
Trussed or cut and stack?
Is there going to be a deck attached to the posts?
Are there any seismic concerns related to the roof system at that point?
Do you need pad specs for the posts?
Steel, or wood posts?
Thank you.
yes snow load Chicago
Shingle roof
cut & stack
yes deck attached 3' above grade and i wont to wrap the wood post with 19"X19" brick colum from grade to 7'above grade
the footings need to be 40" below grade
Ok thank you.
Have you had any of the roof calc's done yet?
In order to determine the size of the beam you need to know the weight of the roof that will be bearing on the beam. This needs to be broken down to the weight if each rafters individual share of the total load and then you can use the scheduals provided by the manufacturer.
You can check the scheduals and other information at this link.
Judgeing from the information you have provided and taking an experienced guestimate of the load you're probably looking at 18" x 3 1/2" x 2ea. lvl's with full bearing on a 8 x 8" #2ob DF post. (*) H-1's inside and out @ each rafter. Heavy steel post caps (CCQ7.1-7.1SDS2.5), and some hardware (LTP4's/lag bolts?) to keep the bottom of the LVL's from splaying in the center.
Fottings @ 36"w x 36"w x min18"d below frost line w/ 8"x 8"oc #4 rebar cages x3. 16" sonotube pier attached to pad w/ 4ea #4 rebar verticles with 'L' base wire tied into pad cages equaly dispersed. CB88 post base w/ pier rebar secured to corners.
Best, THS
