If you are going to make a statement like that then you need a better argument than that. lots of methods that were standard design practices are now obsolete or even considered dangerous.JoshPlumSE said:This is a good design procedure and deviating from it is (IMO) poor practice.
You calculate it. Some tools have been described above. But as said the calculative effort is likely not worth it most of the time, even with advanced toolsJoshPlumSE said:How do you come up with a force deformation curve.

That is what I do whenever I have concerns that I wish to investigate more. It takes a minute of design time. And doesn't involve the complexity of quantifying a semi rigid connection.lexpatrie said:If you design it as both fixed and pinned, you're pretty likely capture the design behaviour in there somewhere .... That's how I view JoshPlum's comment.
bones206 said:Semi-rigid modeling implies you think you can characterize boundary condition stiffness with a degree of accuracy, rather than bounding with the known extremes of fixed or pinned. Unless you feel strongly that you can back up a calculated stiffness value, you should stick with traditional bounding analysis.
