[rofl]Sorry lexpatrie, I love acronyms. 2x deck joist....Dj, Floor joist Fj..
Dblstud, this is one of the other methods that I had thought about as well. Good point about sistering deck joists and "when they rot" is correct, because they most likely will.
Another question has come up about...
I posted something yesterday related to this topic, but I had not yet fully thought through all the issues.
Here is what is going on
Existing conditions:
2 story wood framed house with 2x12 fj that cantilever out 3ft and support the wall/roof load from above.
Proposed condition:
New...
beav-eng, I have already sketched it but I am not 100% sure about the reactions.
I initially assumed that the reactions would be the fbd of the entire new & existing joist section with 3 rxn's.
The beam is 18'-6" it supports roof, floor and balcony. 40psf LL & 60psf LL for balcony. A wood bm...
I am doing a residential project where there is an existing 2 story house and they are adding a new front balcony.
The existing floor joists cantilever 3.5ft and support the wall (roof) above.
Since this isn't the best condition I am adding a steel beam under the wall above so that I can...
Just learned a new term...I had no idea what a plinth was until now.
That makes sense...basically a square reinforced column that the steel column sits on and the masonry retaining wall extends through.
Is this correct?
I am working on a small project and I would like to get opinions about my approach to a problem.
Scope of work is a free standing patio cover roof (300sf) where 2 of the posts are supported on top of a new retaining wall.
Since there are no walls for lateral resistance, and this is southern...
It has been a long time since I have designed a concrete shear wall since the majority of my work is in light framed residential. Last time I did was in 2010 or 2011 and I know that there has been some major changes with the code with respect to slender concrete walls. Unfortunately, I have not...
I realize the mechanics, I guess what I am wondering:
If the backfill is compacted prior to pouring the slab, wouldn't the majority of the cantilever action & tension in the rear reinforcement already be developed?
Then probably a week or so after this the slab would be poured and tied into the...
I am designing a cantilevered retaining wall, 8" poured in place concrete, 6ft retaining for residential. There is a slab on grade behind the wall that I would like to make a positive connection with to the back of the wall at the top.
I would like to limit the potential separation of the slab...
BA, I'm curious how do you go about determining the degree of batter? Is there a rule of thumb? I thought about calculating the deflection but I'm not sure how accurate that would be in this situation.
Thanks BA. Thats a good idea to stiffen up the area between the walls to work as a unit.
The soil is fill down to 50ish foot, but it is considered competent with passive values for the caissons of 150pcf and twice that for isolated caissons.
I have never speced out a battered pile like that...
I have been hired to design the retaining wall system for a hillside residence. Basically the owners house sits about 20ft behind the top of a 2 horizontal to 1 vertical slope with a height of 20ft.
They want to extend the backyard to just beyond the downslope location in addition to a zig zag...
I have a small project, residential site walls to include planter walls that will be retaining 3ft max above grade. I'm curious as to what active soil pressure I should be using to design these planters with.
If I assume code minimum values then my active design pressure would be 60pcf. The...
