Supporting conditions in the analysis of the staircase with the structure

[fthylmz]

hello everyone, take it easy. I'm in some deadlock about my project. 1- I have 124 cm of filling after the foundation in my project and while designing the basement staircase, the staircase stays in the air (is it normal?) 2- I adjusted the support conditions accordingly to analyze the staircase together with the structure. (Have I done it correctly?) 3- I made an analysis with the option to consider earthquake effects in floor design with the semi-rigid diaphragm option checked (is it correct?) After the analysis, the stair reinforcements did not appear in the 'reinforced concrete design-stairs' tab, so I made a stair analysis after the analysis. (Is it true?) Can the forum users and admins who have knowledge on this issue enlighten me? Please it's urgent...thanks

Re: Supporting condition in the analysis of the staircase together with the building

hello everyone, I am at some dead end regarding my project. (is it a normal situation?)

Hello, It is a normal situation if the stairs' elevation and heights are compatible with the architecture.

2- I adjusted the support conditions accordingly to analyze the staircase together with the building. Am I?)

Currently, in version 8, stair supports can be arranged according to solution conditions independent of the structure. Therefore, it is appropriate for you to enter the stair loads into the relevant elements.

3- With the semi-rigid diaphragm option, the option to consider earthquake effects in the flooring design is checked I made an analysis (correct?)

By ticking the option, analysis can be done

After the analysis, the stair reinforcements appear in the 'reinforced concrete design-stairs' tab medi and so I did ladder analysis after analysis. (Is it true?)

If the stair supports are arranged according to the solution conditions independent of the structure and analysis and stair analysis are made, the reinforcements appear in the Stairs Reinforced Concrete dialog.

Finally, is the stair reinforcement axle drawing correct? If not, what should I do

In the program, stair reinforcement axles and reinforcement drawings have been developed for straight arm stairs. Good work

Re: Supporting conditions in the analysis of the staircase together with the structure As I understand it, we will draw the reinforcements of the spiral staircases by hand. Also;

2- I adjusted the support conditions accordingly in order to analyze the staircase together with the structure. Therefore, it would be appropriate for You to enter the ladder loads into the relevant elements.

In version 8, there is 'supporting condition for solution with structure'. I understand that you do not have such a feature from what you said, did I misunderstand, did you want to tell something else? My main question is that I want to solve the ladder and the building together in the project I sent. I made the support on the ladder accordingly. 1-Are my support conditions correct for the solution with the structure? 2- Since I solved the ladder together with the structure, I did my analysis by creating a semi-rigid diaphragm, is it true? 3- In such a solution, is it necessary to enter the ladder load to the relevant elements? Thanks...

Re: Supporting condition

in the analysis of the ladder with the structure there is a 'supporting condition for the solution with the structure' in version 8. I understand from what you said that there is no such feature, am I wrong? Did you want to tell me something? Is it necessary to enter the stairs?

Currently, the stair supports cannot be arranged according to the solution conditions together with the structure in Ver 8. Arrange the supports according to the solution conditions independent of the structure and enter the stair loads. Is it correct?[/quote] You can make a semi-rigid solution. Even if it is blocked, semi-rigid diaphragm can be a solution. Good work
