pattern hinges karamba

Hello all,

I am trying to make a beam grid that is connected as shown in the picture. There are no primary and secondary beams, but they are based in the zollinger system, where beams are being connected with hinges in the midle of the one in the different dirrection. On the picture the different set of beams are shown in different colors (green and red)

I know that every beam would also have a middle point in order for Karamba to interpert the connectivity, so when I tried to describe this hinge connectivity with the simple components of joints in karamba I also got connections in the mid points of the beams.

Do you have any ideas how to achieve this beam connectivity as shown in the pic in Karamba?

Thank you!

Popi

Hello Popi,

did you try out the 'Joint-Agent'-component?

Hey Clemens,

I believe that I should use this component and specify the points of where the hinges would be, but I do not want to do this manually. Do you have any suggestion how to import the beams with 3 points but still get the hinges points for the karamba analysis?

Thank you!

This is the stage I am in. Any ideas on how should I describe the beams so that they are connected, but also can seperate the hinge points?

Thank you!

I have found a solution for the points, but not for the beams.

I need to place them in different lists so that I define 2 different beam sets.

Please help :)

Hi Popi,

you are on the right track. What I suggest is that you set all the green members as one ID and the red ones as another ID. Then you can define different two different joint releases according to the beam IDs at specific points for each colour.

I have a more general question. How is Karamba dealing with 3 elements meeting at the same point? How could the order of connection per element be determined?

For example if we have 2 columns with diagonals and a beam of a floor. The supports are on the end of the columns and the diagonals arehinged connected to the columns and the columns to the beam.

Thank you!

You cannot determine the order of connectivity, therefore it is important to identify the different beam sets as different IDs so that you can control the type of release to assign. Using the Joint Agent component, you can define at which element the joint will apply to. If you look into the examples that are included with the installation of Karamba (often a shortcut is installed automatically on your desktop, you can preview how exactly the Joints can be defined)
