karamba replied to jiaxing's discussion 2 emergent problem to solve in karambaa in the group karamba
"If the bolts are neither prestressed nor fitted screws all the bolted connections above should be modelled as hinges with zero rotational stiffness about the local Y-axis. The reason is that the diameter of screws holes is normally somewhat larger…"

"maybe this way is more directly for me to understand  the translate and rotate on detail joint  model ,now I'm confused by this 4 joints 12 3 4 "

"Dear Clemens Thank u very much about those suggestion above. about the book <Structural Steel Designer's Han - Roger Brockenbrough> this is what I find , but did not find the stiffness of hinge in it "

karamba replied to jiaxing's discussion 2 emergent problem to solve in karambaa in the group karamba
"Dear Lu, if you are not sure about the stiffness of a joint, choose zero. For steel structures with standard cross sections (which do not buckle locally but develop yield hinges) this always lies on the safe side. For stiffness values of steel…"

"Dear clemens thank u so much for this solution of eccentricity. it can solve my problem now. and I have another question about the cross joint cr-start ct-end how to identify the stiffness above, do we have some standard? now I need to define some…"

karamba replied to jiaxing's discussion 2 emergent problem to solve in karambaa in the group karamba
"Dear Jiaxing, it is possible to define eccentricities on beam cross sections. This can be done either per beam or per cross section (see manual). By default elements which meet at a common point are rigidly connected. In order to solve problem 2…"

karamba replied to jiaxing's discussion about spring caculation in karamba in the group karamba
"Dear Jiaxing, it seems as though one of the springs is not connected to the frame (see attached file). Try to pull the endpoints of the springs to the berep before including them in the mesh. Best, Clemens "

"when the spring add into caculation , it turn to be red and saying cant solve static system, i checked the support pt and other components, did not find which part is wrong in this caculation , pls help"

Box Clustering

"hey daniel  could you give some case( gh files) about some kangaroo stuff in this video? I think you used the boxcollide item    . and I tried to figure out how to use this item but failed . It would be really useful for me  best…"
