Discussion about a model for buckling of a spreader beam
In Mw is very fast to apply MPC by equation. So I have utilize equation between two node for buckling analysis. Imagine a spreader beam subjected to compression load due to sling angle. The beam is free to rotate on the space. I have applied balanced loading, minimal support and constraint equation between two nodes. Obviously, due to minimal supports, many modes are rigid. Setting shift point to 1.5, after some
attempts, I have found the result displayed. I attach some pictures and relative LIML file.
