See image attached. How would you reinforce this stairs-slab connection? Stairs are sitting on top of the RC slab so its not our typical slab to stair connection.

Ive made few calculations and there is a difference in moments if the support is horizontaly sliding or not. So its realy up to designer to decide and later on to reinforce the stairs. I dont think the stairs would break if the support is sliding. Ithink exactly opposite

Hello! Please see image attached. Whats you opinion on not conecting the RC stairs to the RC foundation slab? Basicaly the stairs are siting on top of the RC foundation slab and ar not connected with and rebar. The other end of the stairs is conected with the RC wall using U bars (tenssion lap)...

There wont be any compaction behind this wall! Only deposited material

Hello! Please see pictrue attached. My code (EUROCODE) defines that for contoling deflecion of RC slab one must see that the deflections are under the value of L (shortest slab span) divided by 250. Wich value for L would you take for this scenario? The walls are made from confided masonry and...

Ill guess ill just lower the safty factor from 2 to 1,50 for overturning. Other than that I dont see any other solution

I dont think this picture describes my scenario. What you have on the picture is an full soil profile behind the wall. I dont have this. Please see my picture

BridgeSMith...any chance for that picture? :-) @PEinc You mean the shifting of the force to the half of the height of the backfill and not on 1/3 from the bottom?

Bridgesmith thanky you very much! Any chance you could post an image that your text is relating to?

Hi! Please see attached image. How to calculate the horizontal pressure that the backfilled material will have on the retaining wall? The material will be deposited and will have this trinagular shape behined the wall. Usualy we are presented with problem that say that the material is compacted...

Pure magic! :-)

Please see image attached. Its an RC container. No matter what the width of the water block inside the container is, as long as the height of the water bloack is the same in all of 3 containers, the pressure on the bottom of the wall on all of the 3 containers will be the same. The walls will...

Heres an more detailed look. All masonry bearing wall will be connected with confining RC elements! The roof is flat RC slab!https://files.engineering.com/getfile.aspx?folder=845680b7-431d-418e-8aa1-513c731b4980&file=Capture.JPG

Hi folks! Please see attached images. The 1st floor slab is canterlivering from the groundfloor walls. Would you say that the 1st floor RC confining element (marked with "?") is necesary, since there is another one at the end of the wall? Thank...

Thank you:-)

"The way we do it, all the horizontal bars would be discontinuous at a contraction joint" Do you provide also an small groove on one side of the wall? (smaller section heigth) "The wall is designed on a per-foot basis, so the stem wall sections are structural adequate independently." I...

Agree, crack cannot be prevented, but with reinforcement they (crack width)can be controled with horizontal reinforcement. But again, this MUST be related to joint spacings. 100 feet long retainng wall will have more vertical cracks then an 30feet long retaining wall, if both are without any...

I dont understand how the control joint and horizonstal reinforcement (for T&S) in retainng wall are NOT related?!?! This doesnt make any sense! Logicaly I would say: if I provide more horizotal reinforcement in the retaining wall, I could put two control joints more far apart, and vice versa.

"Contraction joints shall be provided at intervals not exceeding 30.0 ft" As previously said, construction joints are to allow shrinkage cracks at the joint location. I understand. But this 10 feet distance is a very short distance. I must say Im a bit suprissed. One question, if you provide...

@hokie66 "In your case, I would use two, at 10'" I dont understand you....are you talking aboth control joints or....?
