Karamba3D is an interactive, parametric finite element program. It lets you analyze the response of 3-dimensional beam and shell structures under arbitrary loads.

Karamba3D is being developed by Clemens Preisinger in cooperation with Bollinger und Grohmann ZTGmbH in Vienna.

What are parlay bets in sports? 2 Replies

What is a parlay bet, and how does it work, I’ve heard people mention it can lead to big payouts, but is it a good choice for beginners, or is it too risky to combine multiple bets into one?Continue

Comment by Karamba3D on February 20, 2013 at 5:44am: At the moment there is no direct way to define double IPE cross sections.

You could set up a cross section table with the exact cross section properties of double IPEs, but set their type to e.g. Box-cross section. When displayed you would see box cross sections which have the physical properties of double IPEs.

Comment by Mohammad Azinkia on February 19, 2013 at 6:56am: How can we use double cross section in karamba for e.g. we want use double "IPE" for column or beams.

Comment by Karamba3D on February 19, 2013 at 3:55am: You get the optimized cross section for each element by disassembling the model and then disassembling the elements. In case this does not work as intended with Karamba 1.0.2. send me an e-mail (info@karamba3d.com).

Regarding your previous post: the cross section optimizer computes the cross sections in such a way that their utilization is less than 100% for all load cases. If you have e.g. wind blowing from two directions create two load-cases (see manual).

Clemens

Comment by Mohammad Azinkia on February 18, 2013 at 7:28pm: In huge project, if we want to construct our structure how can we have output of the cross sections optimized?here I just see a cloud of fonts.

Comment by Mohammad Azinkia on February 18, 2013 at 7:24pm: another question: we should analyze structure in x and y by force to analyze what is structure reaction and cross section.Is it any way to have maximum cross sections between x and y direction?If yes how?

Comment by Mohammad Azinkia on February 18, 2013 at 3:38pm: Thank you Clemens!! Best help as always.

It works well.

Comment by Karamba3D on February 18, 2013 at 12:48pm: Hi Mohammad,

there are two things you have to change in your definition:
- flatten the element input at the assemble-component. Otherwise you get three different models instead of one
- Feed a list of cross sections into the cross section optimization component.

Best,
Clemens
