Beamless flooring and miscellaneous faults

[ferhat35]

they asked for beamless flooring for the last floor in my project and I will have questions about the project as I have never done it before 1) I made the 4th floor slab as a beamless slab except for the outer frame, but the program detects it as a beamed slab, how can I fix it? 2)4. I did not define a table in the column headers on the floor and entered the header thickness as '0' (I did not see any trays and headers in the applications) do you think this is a problem? 3) For the cantilever protrusions at the approach distance on the other floors, I got the cantilever beam from the beam, is this a very troublesome situation or how can we solve it? 4)4. Do you think it would be better if I make the floor console protrusions like a beamless floor and put no beams? I WILL BE GRATEFUL IF YOU CAN HELP. Thanks in advance. appendix:

1) I made the 4th floor slab as a beamless slab except for the outer frame, but the program detects it as a beamed slab, how can I fix it?

Hello, It is not perceived as a beamless slab because the columns are connected with beams. All columns are connected by beams. If what you mean here is to put the reinforcements in the form of flat + pillars, you can change the reinforcement type to be flat reinforcement at the top + bottom with the "Edit Reinforced Concrete Calculation Axis" command in the Flooring Assistant toolbar. I entered the thickness of '0' (I did not see any table and header in the applications) is this problematic for you?[/quote] Since all the columns are connected with beams, there is no need to make a punching verification and therefore to define the column cap.

3) For cantilever overhangs at approach distance on other floors I came out of a cantilever beam from a beam, is this a very troublesome situation or how can we solve it?

In terms of analysis model and data entry n is not a problem.

4)4. Do you think it would be better to make the floor console protrusions like a beamless floor and not put any beams?

It is a recommended modeling to enter beams in outer frames. However, in the model, the beams will not be less than 3 times the floor thickness. does not satisfy the condition. (TDY 2007 item 3.4.1.1.b. and TS 500 item 7.3) Note: I recommend you to analyze according to the semi-rigid diaphragm method.

In addition; 1st and 2nd in TDY 2007. There are sanctions for beamless floors in earthquake zones. It would be appropriate to consider Tdy 2007 clauses 2.5.1.4, 2.5.3 and 2.5.4 for un-beamed flooring systems. Good work
