The suitability of the stair position on the filling ?

[iek58]

hello, the contractor wants a filler in the attached project. but since the engineer friend before me used normal beams with hollow floor slabs, I was asked to make a hollow block solution. In the construction, the column concrete of the ground floor has been poured. that's why I have columns and stud beams that I can't run on the same axis without being comfortable with me... Here is the best project I could create due to my adherence to "architecture" and "ground floor column application"... I have a few questions for my experienced colleagues 1- to add to the current project- Do you have anything you want to remove? 2- Since there is 50 cm infill on the radial foundation, I started the staircase at +50 level and set the edge of the staircase that meets the infill as "fixed support" to solve it together with the structure. I fixed the edge corresponding to the curtain with a "curtain" and the upper level of the stairs with a "beam". is it true? Since my 3-floor height is 3.5, 20 cm curtains on both sides of my elevator are not accepted due to regulations. In this way, there is no problem in the analysis. Is correction necessary? (The previous engineer friend solved the 20 cm curtain (he may have defined a separate floor for the basement curtain and made "0.5 + 3&quot) 4- Apart from this project, what do you think about connecting the stairs to the hollow floor slab?

Hello. My Suggestions (Assuming that this floor plan continues on the upper floors and commenting without checking the calculations)

the contractor wants a hollow block in the attached project. During the construction, the column concrete of the ground floor has been poured. Therefore, I have columns and stud beams that I cannot operate on the same axis without getting comfortable with me...

How will you fulfill the contractor's requests with the Demo project? (You cannot print out drawings and calculations.)

1- do you have anything you want to add or remove from the current project?

--Elevator curtains P01-P03 better be connected in the long direction, --beams should center the columns

2- Since there is 50 cm infill on the radial foundation, I started the staircase at +50 level and set the edge of the staircase that connects with the infill as "fixed support" to solve it together with the structure. I fixed the edge with "curtain" and the top of the ladder with "beam". Is it correct?

--The ladder's support is not correct, fix it, --Put a flood curtain where the ladder ends on the foundation and support the ladder,

3- since my floor height is 3.5, my elevator has two floors. does not accept the 20 cm curtains on the side of the building as a source of regulation. This way, there is no problem in the analysis. Is correction necessary? (The previous engineer friend solved the 20 cm curtain (he may have defined a separate floor for the basement curtain and made "0.5 + 3&quot)

See TDY20017 3.6.1.1

4- apart from this project, what do you think about connecting the stairs to the hollow floor slab?

On the floor as you did here, the staircase should be supported on a beam of sufficient rigidity. Unver ÖZCAN

Thank you for your answers Mr. Unver,

--Elevator curtains P01-P03 better be connected in the long direction,

how do we do the long direction fastening application?

--The ladder's support is not correct, fix it, --Place a basement curtain where the ladder ends on the foundation and support the ladder,

the basement curtain was not built. Manufacturing was done according to the old foundation plan. Is it possible to connect the lower end of the ladder as it is?

Hello. The curtain will be connected to form a frame in the long direction. If additional CERCEVE Raft flooring has been made, you can build a 50 cm high, 100 width and 115 cm ladder width platform on it (it would be better if the raft foundation is rough with this platform) and sit the ladder.

Thanks for your answer, Mr. Unver,

The curtain will be connected to form a frame in the long direction. additional FRAMEWORK

I did not apply this

You can build a platform with a width of 115 cm and a ladder width (it would be better if the raft foundation is rough with this platform) and you can sit the ladder.

I made the application. Can you check the accuracy? however, I converted the ribs (4 pcs) exceeding 1- 4 meters into tape. the remaining floors are still referred to as ribbed flooring. Is it okay to use tape and rib on the same floor? 2- There is a short beam between S15 and S16. When analyzing 4 floors, I get a warning of insufficiency in this beam on the ground and first floors. How would you suggest I overcome this? Or, what kind of solution do you think is to attach the stud beam (K43) to the beam between the columns (K44 and K45, which are divided into two due to modelling) to S15 or S16?

Hello

I made the application. Can you check the accuracy?

If there was a sprout reinforcement, the size would be sufficient. The size I gave before is reasonable.

cassette and rib Is it okay to use it on the same floor?

No

2- There is a short beam between S15 and S16. When analyzing 4 floors, I get a warning of inadequacy in this beam on the ground and first floors. How do you suggest I go over it? Or what solution do you think it is to attach the stud beam (K43) to the beam between the columns (K44 and K45, which are divided into two due to modeling) to S15 or S16?

It is better to throw a beam between S15-S01 and S16-S21 column. a good solution Unver ÖZCAN

Thanks Unver,

A better solution is to throw a beam between S15-S01 and S16-S21 column.

we reached a more appropriate result with your solution. When analyzing as 4 layers 0 :04 ******************** CANNOT NETWORK FOR "GROUND FLOOR" IN "D30".*************** ***** 0:04 ******************** CANNOT NETWORK FOR "GROUND FLOOR" IN "D32".************* It gave an error *********** and completed the analysis 1) what is the cause of the error I could not find the D30 and D32 slab in the formwork plan what is the reason? did I make a wrong definition? 2) I applied the supports of the stair and I copied it to other floors. When the stairs started at +50cm on the first floor, it was copied 50 cm above on other floors as well. I brought the level to 0 and brought it to the level. Are the stairs defined correctly? 3) When I analyze the stairs, they seem to be connected lower than the level they are (picture attached) finally 4) Typical beam failure in NZ30 and NZ32 cassette decks there is. how can i solve it?
