I CAN'T SAVE THE ELEVATOR CURTAINS

[emrebagdu]

it says I can't save the elevator curtains on the floors, slip safety is not provided. The curtain of the moon saves the lower floors. I wonder if I am doing something wrong, if anyone can examine the project and give information, I would be very happy

No one to help????

Hello there; I did not see a problem with the modeling of the elevator curtain in your project, when we look at the reports, it is seen that the sections of the problematic areas are insufficient. As a solution, you can increase the thickness of your elevator curtains, increase your concrete class, or in general, you can reduce the effects on the elevator curtain by adding other curtains to the carrier system. Apart from these, I would like to point out two problems that stand out at first glance in your system: - Your basic definition is wrong, as follows; If you wanted to make a raft with beams, it is imperative that the main beam passes under all columns, and the columns should never step on the raft. If you wanted to define a slab raft, this time there should be no outer foundation beams. - Your acceptance of a rigid basement seems to be problematic because your basement does not seem to have enough perimeter curtains. Best regards.

Hello, I could not see any situation affecting the curtain results in the superstructure data entry in your project. However, I think the carrier system is very irregular. To solve the problem, it would be appropriate to improve the carrier system especially in the y direction. In addition, material strength can be increased. Other project determinations and suggestions are as follows; **While defining the foundation in the project, the outermost columns and foundation beams were connected and a raft slab was placed in the middle. This basic system is definitely not suitable for the program algorithm. In this case, the effects of the columns sitting on the raft slab are not taken into account on the raft slab. When defining a beamless raft slab, a closed area should be created with the slab edge and a raft slab should be placed in this closed area. **Curtains can be modeled as shells. **In the geometry control, the level of the D042 slab on the 4th floor is incorrect. The reason is that the K449 beam is different from the elevation of this floor. To solve the problem, a floor edge parallel to K449 can be drawn 1 cm from the left side of the K449 beam. Good work

Greetings.. I have the latest version installed and I edited with it. In 1-project, the base cutting ratio is 0.29 for the x direction and 0.43 for the y direction. I turned a few columns to the screen so that the x direction also goes above 0.40. so I got R=6 for the mixed system. 2-I modeled all curtains as shells. as well as basement curtains. 3-I reduced the torsion a little bit. For the case of 4-earthquake, I slightly reduced the stiffness of the curtains on the relevant floors. I added a colon to the corner connections (it may not be, I'm doing it for the connection in the drawing) now the system does not give an error....

Thank you very much for your help, but now I tried every way you suggested but my problem was not resolved, when it comes to the trouble with the foundation, the choice and solution of the foundation was not finished yet. Thanks again for your warnings. I examined the project you sent, but by setting the system to mixed, the slip security on the curtains is not removed. When I select the earthquake zone at the 4th degree, there is no problem, but when my earthquake zone is 2, when I enter earthquake zone 2, the slip safety problem on the curtains appears, I still haven't been able to solve it.

Dear forum officials, the phrase I have stated below is exactly taken from the answer." While defining the foundation in the project, the outermost columns were connected to the foundation beams and a raft slab was placed in the middle. This foundation system is definitely not suitable for the program algorithm. In this case, the effects of the columns sitting on the raft slab are not taken into account. When defining a beamless raft slab, a closed area should be created with the slab edge and a raft slab should be placed in this closed area. According to this statement, can we not define a raft after defining a continuous foundation without amplification only under the surrounding columns. And I understand that we can't make a raft without defining the foundation beam for the surrounding columns, except for the beamless raft, I understand that if we want to do this, it would be correct to make a raft without beams with the floor edge. Thanks in advance for your answers, it needs to define the rail by defining the basic beam.

As you said, your system will be wrong if you only turn the outer columns with a continuous foundation and define the interior floor in ide. unfortunately, there are many projects that have been passed and approved with fi16/40 upside-down equipment. In fact, the IDE would be really helpful if it showed this as an error in the next update.

What do you think should be taken as the rigid floor number due to the irregularity of the basement floor curtains in the system?

What do you mean by curtain irregularity, can you explain a little?

greetings.. I have the latest version installed, I edited with it. 1-in the project, the base shear ratio is 0.29 for the x direction and 0.43 for the y direction. I put a few columns on the screen so that the x direction goes above 0.40 So I got R=6 for the mixed system.

To get R 6, alpha-S must be greater than 0.66. A value less than 6 between 0.4-0.66 is entered, so the program returns the required value.

I think the intention is that only a part of the basement is curtained; In this case, counting the basement as a rigid floor and separating it from the earthquake calculation will not take a very realistic analysis, I think, if the basement floor number is -1, if I were you, I would choose the rigid basement number -2 and I would prefer that the basement be included in the horizontal load calculation.

Types of shallow foundations we use: 1) Single footings 'columns press on single foundations' 2) Continuum (unidirectional beam) foundations: 'columns press on beams' 3) Two-way continuous (grid) foundations: 'columns press on beams' 4) Beam raft foundations placing h/3 slabs between the beams of the grid foundation); 'columns press on beams' COLUMNS DO NOT STOP FLOORING! 5) Raft (matte) foundations: columns press on the raft slab.

What do you mean by curtain irregularity, can you explain a little?[/ quote] I meant that the basement floor is not surrounded by curtains on all 4 sides..
