Curtain floor offset calculation

[candan]

Hello there. I want to learn how ideCAD calculates curtains. Appendix 1) Is it necessary to define the wall as a finite element and a polygon column when calculating stiffness and center of mass? Or do these definitions change the result? 2) In the file I uploaded, I cannot affect the point load on the curtain at the peak. I want to check the result of the program with the Floor offset in the manual calculation. 3) It works as a rigid diaphragm at floor level, right? Or do I need to make any definitions for this? I would be glad if you help. Have a nice day..

1)Does the curtain need to be defined as a finite element or a polygon column when calculating stiffness and center of mass? Or do these definitions change the result?

You may not recognize it in two ways, but one is a rod and the other is a rod. It is solved as a shell. Since the system setup will be different, the rigidity and center of mass calculation may be different, especially in asymmetric systems, but it does not matter in symmetrical systems.

2) In the file I uploaded, I cannot apply a point load on the curtain at the apex. I want to check the result of the program with the Floor offset in the calculation manually.

You can refer to the information given below regarding the load definition. There is areal load in shell models, point load in rod models.

3)Doesn't it work as a rigid diaphragm at floor level or not? Do I need to make any definitions for this?

If there are slabs in the system, the rigid diaphragm is automatically created.If there are gaps or no slabs on the slabs, the program can make solutions with more than one rigid diaphragm or without a rigid diaphragm depending on the options you give.

1)When calculating stiffness and center of mass, should the curtain be defined as a finite element or a polygon column? Or do these definitions change the result?

You may not recognize it either way, but one is resolved as a stick and the other as a shell. Since the rigidity and center of mass calculation system setup will be different, it may appear in different places, especially in asymmetrical systems, but it does not matter in symmetrical systems.

2) In the file I have uploaded, I cannot affect the point load on the curtain at the apex. I want to check the result of the program with the Floor offset in the calculation manually.

You can refer to the information given below regarding the load definition. load is point load in bar model

If the system has tiles, the rigid diaphragm is created automatically. If there are gaps or no slabs on the slabs, the program can provide solutions with or without a rigid diaphragm, depending on the options you give.

Thank you very much. I have two more questions. 1) When we define L curtains, are the curtains calculated separately? Does it make separate calculations whether it is a panel or a polygon? 2) Where is the effect of the point horizontal loads on the curtain shown in the report?

Polygon column If you define the element as a polygonal bar element and the reinforcement is made like a column. If you define it as a panel, each element enters the analysis with its own stiffness. If you do not define a panel and solve for acceptance, each finite element has its own stiffness. All joints are solved connected to each other and reinforcement is in tdy2007 It is done based on the specified wall reinforcement conditions. The external loads you affect on the wall can only be seen in 3D if the wall is modeled as a shell. If it is not modeled as a shell, you can display it in the report by selecting the user defined point and element loads option under the optional report/other heading.

[ 1) When we define L frets, are frets calculated separately? Does it make separate calculations whether it is a panel or a polygon? 2) Where is the effect of the point horizontal loads that we apply on the curtain shown in the report?

If you define a polygon column, the element becomes a polygonal bar element and the reinforcement is made like a column. If you define it as a panel, each element enters the analysis with its own rigidity. If you do not define a panel and solve for acceptance, each finite element has its own stiffness. All joint points are solved connected to each other and reinforcement is made on the basis of the curtain reinforcement conditions specified in tdy2007. External loads you apply to the screen are only visible in 3D if the screen is modeled as a shell. If it is not modeled as a shell, you can view the user defined point and element loads in the report by selecting the option under the optional report/other heading.

Thank you very much for your answers. However, I also wonder where I can see the effect of the change in point load value I act on on the horizontal displacement movement? For example, in which heading can it be seen as this much for a 100 t load and this much for a 200 t load?

Thank you very much for your answers. But I also wonder where I can see the effect of the change in point load value that I have applied on the horizontal displacement movement? /quote] If you define the external load in a load situation that you created, you can only see the deformation of the structure in that load situation in the 3D frame.

If you define the external load in a loading situation that you create, only that load you can see the deformation of the structure in the 3D frame. You can also see the displacement values when you move the cursor over the joint.

I will ask one last question and I will set you free. What is the unit of displacement values it shows?

What is the unit of the displacement values it shows?

Right click on Design settings on the building tree, then click on Design Settings. The design settings will open. Whatever the deformation unit sees there is also the deformation unit in 3D that is it.

You really helped a lot. Thank you so much. Have a nice day.
