REQUEST: Add span lenght parameter to beam #37

Open marciosarto opened 3 years ago

Describe the solution you'd like A extra parameter for beams related to the real span lenght would be really nice to facilitate the SLS analysis of beams, and it's a current requirement of a timber beam in Beaver.

Would it be possible to add this parameter alongside with the buckling lenghts definition on beams? Then the KarambatoBeaver component we are working would work perfectly!

Is it maybe more versatile to have a displacement limit in local Y- and Z-direction for each beam for SLS analysis instead of the span? In case of cantilever beams one would have to set the 'real' span to double the cantilever length. Would this not be confusing?

Well I got the issue on cantilever beams, it's a question that we are still thinking through on Beaver. However a parameter for a span length would be beneficial as in timber structures we have to check for 3 different deflections limits that are all function of the 'real' span, that's why I think one input would be better, because we can latter define the deflection limits for instantaneous and long term deflections.

But I agree it might be confusing, for now we have a definition for a TimberFrame in Beaver if the frame is a span beam or a cantilever beam, but we aren't still convinced this is the best approach.

Maybe it would be best to have a UserData-mechanism for K3D objects similar as described here: https://developer.rhino3d.com/guides/rhinocommon/plugin-user-data/
