I have had this task in my mind for some time.
How would this be best approached using karamba?
I can only think of iterative process with optimization solver employed.
Lets say i want to build a pier segmentally step by step. build formwork --> pour --> build formwork --> pour another segment …
My aim is to achieve desired shape after completion but due to deformations i have to build it a bit off at each step.
I need this type of calculation.
Start with approximation stress free line of first segment. Calculate --> use deformed axis as base for another step --> add new segment, turn off loads for already deformed built part and calculate --> use deformed shape and add new segment, turn off loads … --> repeat --> find differences between desired nodal positions and deformed calculated ones, play around with initial nodal positions and iterate until differences are within tolerance.
This is fairly easy when i construct it in my mind but i dont know how i would automatically increase number of paramaters in GH which you need to fine tune (two params for each node X Y) when you increase number of discrete parts of the beam for example…
Any thoughts? Thanks
