Short Panel Objects

[serky]

Hello, In the project I am working on, the thickness/length ratio of the elevator curtains is less than 1/7. Is it a correct approach to model these curtains as seen in the screenshot below and change the aspect ratio from the curtain settings? Other methods I can think of are modeling the projections on the curtain ends as panel objects or modeling the whole system as a polygon column. Which of these options is more correct? Is there any other method you would suggest? thanks good work

It is a correct approach to model the panels as shells and enter data as shown in the picture. The projections at the curtain end can be made of columns as well as panels. If you leave it as a column, the column element will be split into finite elements in accordance with the panel finite elements. Other methods you wrote can also be applied. It is also possible to enter a polygon column. Since the polygon column will be a single element, its inertia will be greater, and the rigid arms of the beams connected to it will be long. In addition, beam, panel or slab edge cannot be defined between the arms of the polygon column, since the polygon column is a single element. As the elements get longer, it may be more appropriate not to choose to enter polygon columns. Changing the screen aspect ratio does not affect the analysis result. This ratio is a parameter that determines the curtain end zone formation conditions.
