Grasshopper

algorithmic modeling for Rhino

Hi,

I'm trying to model on Karamba 3D the tension acting on a general curve due to prestress forces.

My first approach was to subdivide the curve and then define the forces acting perpendicularly to the curve (one vector force for each point of subdivision). This approach it's not reliable because doesn't give acceptable values in terms of Shear and Bending Moment acting on the curve, even with high subdivision value for the curve (indeed the model seems to be not really responsive to the number of subdivision for the curve).

Theoretically the tension acting on a curved line could be modeled as a continous load acting perpendicularly to the curve.

So I would like to know if there is some method in order to have a uniform line load acting perpendicularly to a curved element.

I could be interested in some algorithm, strategy, additional component or I would like to know if it could be possible modify the source code of some Karamba component.

Thank you in advance for your help

Hi Simone,

at the moment (Karamba3D 1.3.1) one can only have straight beams so you need to shatter your curve into small pieces. The you can define uniform line-loads on the pieces.

Best,

Clemens
