Hello everyone,

I am trying to calculate support forces in Dynamo.

this is my situation:  
 ![image](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/4/6/462bbc79389b09586a8062cf2a2973644f8f3ca8.jpeg)  
supports can vary between 5 up to 21 supports, all at same distance.

By the way:  
the beam will be devided at the same place as the support so there won’t be a bending moment on top.

thanks!

Sorry, but if not anyone have a lot of extra time and wants to solve this for you, you’ll do better if you can show that you have tried by yourself first.

If you only need reaction forces just create a surface (or even a volume) for each force and then divide the surfaces (or volumes) at the midpoints between supports, group by nearest column and finally sum the total area (volume).

i did try it myself

it looks like this:

if it’s between a specific range, than it bears a x value.

but i’m not happy with it.
