Question software for decks with different material options

Hello,

I'm looking to use free software that will show deck piers not required when attached to the house.
When using decks.com or Home Depot deck designer, these software place footings adjacent to house.

Do-It-Yourself Deck Designer (Home Depot):


Decks.com post view:


and Simpson Strong-Tie:


I could be missing something but I do believe piers adjacent to house foundation seems odd and placement could be better or some piers removed when attached to house. The Decks.com and Simpson Strong-Tie sites did some of that but not on the side.

I'd really like to not have footings and posts adjacent to home foundation, factor in posts that are steel or 6x6, and better wood species that allow beams and joists that allow for longer spans. I'm planning on beam flush with joist construction.

Thanks,

Jason

Please post a picture of your real house where you want this deck.
Is this a brick sided house?
If so you can not just attach a ledger to brick, it would need to be through bolted.
Is the deck going to be a second story deck like you show in the pictures?

CODE Says Other Wise , so They will Bust You on that .. or Ask for some Stupid Number that States needs to Issue = Equal to - BS

I'd say with Use of Nice Expansion Joints ~ You'll be Find and Totally Free Floating or Self Supported . .
Tq. onto Building with (( Nice Big Strong Bolts )) But only Use Min. 15-20 Ft. Lbs into
(( Main Frame on (( Home - Construction Band )) between floors . . .
NOT 50-60 ft. Lbs. - like most persons would be doing ..

Then there is the Brick Siding Question and Where on Home .. How many Person Rated etc.

In Fact - If this is to be Used in any-manor as a Fire Escape then it has to be __ Totally Free Standing & Self Supporting - Period ! ( Maybe also * Covered * )

Expansion Joint Materials to between Building & Deck Landing acting as a Bumper . .
It's been awhile , so might be something New out there - would serve Better . .

If U Design so that System is 85% on the Other Supports & U - Up Grade two Sizes on Support Beams
Then You'd be Cantilevering toward the Home in a Manor of Speaking ..

If You Deck was to be 10ft out and You place 1 @ 10ft Out
1 @ 6ft Out , then Last one Heading toward Home 2ft Out - You'll Miss Your French Drains
etc. (( Blame it all on French Drains )) so U have 4ft Spacing , but never get close to Homes Out Wall . .

If I'm Reading what Your asking . . also Add a Double Band on Outside & Inside - just for Good Measure
Use Torx - Screws as those are Rated 10K Lbs

Tried to Insert Picture of Hardware , but No Go ~ Lag

I'm a DIYer home owner and just seen somewhere about brick why maybe want free-standing. I think I understand why you want picture. T1-11 is in bad shape, will be replaced with Hard-Panels. Here are a few:

You'd be Surprised Old T-11 is Tough Stuff , Power Washing & Restore A Finish would be New again ..

Hardi - Panels have a lot of Issues with Butt Joints , why Contractors By 20 ft long Pcs to stay hell away from Joints. then Time & Cost You'll be 2-3K .. also these Places Selling Cheap & Ware Houses Type sales
Stuff is Generally Rejected from Factory or been Laying in Pouring Rain for 7 Months . .

On that Home One side is Cantilevered and Other side is Supported ..
, Only Side You have Left would have to be Free Standing - Fully Supported . . - Just Cantilever Backwards
Is all ..

If You Really have a Soft Siding Issue - it's an Issue with the Fact everywhere Builder buy 8ft Long Lumber

No One if Buying 12ft sheets , and so the Seam Between the Upper & Lower will or has Caused Issues . .

so If You really have to Pull it all on 1 side , where the Rain is Wind Driven ( WOW )
Plan on Pulling all Insulation and Spray Foaming it or using ROCK WOOL - Insulation it is 100% Better
Won't ever get a Nasty like Fiber Glass . . Crap .. 80% Better Sound Deading , Fire Proof , Has much High R
Per Inch the Glass . .

In order to use ledgers, your joists must be perpendicular to the ledgers. (So your drawing would need to be modified). However it gets a little complicated to turn a corner with ledgers, since a ledger cannot (is not allowed to) support a beam. So your beam (or beams) would need to sit in pockets in the load bearing wall. A deck like this would likely need to be designed and approved by a structural engineer in order to get your permit approved.

I want to remove piers and posts circiled in orange. Can I reposition, if necessary, piers and posts circled in red? Here's my config I put in for Simpson Strong-Tie site:
Footer depth 30"
Min. PSF
Dead Live PSF 40
Dead Deck PSF 10

Concrete piers
Souther pine
Joist Size 2x8
Beam size 2x8
Post size 6x6
no bracing
fastener type: galvanized screws

also, if I go from 2x8 beams to 2x12 beams, the site recalculates from 6 to 5 pier and post on the right 32' side of the home. Is it worth doing that?

In your drawing, those posts are needed next to the house because they support beams. You can only get rid of the posts if the beams sit on the exterior wall and are restrained with lateral load devices. I mentioned, if you use a ledger on each side to eliminate the posts next to the house, you still need 1 or 2 beams at the corner (depending on how you want to frame it), your joists need to be perpendicular to your ledgers, and those beams need to sit on the exterior wall and be restrained in the same manner.

in previous example, can those posts circled in orange be removed if the posts circled in red are re-positioned?

how about in this configuration:
joists 2x8
beams 2x12
posts 6x6
southern pine



seems like there should be ability to back off post&pier circled in orange away from the home some
