Ok, all the elements convert to global coordinating system and get [K]. What about the forces, linear forces and moments? Also needs to be convert to global k.s.?
I am trying to learn how to solve/calculate forces for linear frames and grids, like this:
- frame:Link
or:Link
etc.
- grid: Link
etc.
I have to learn how to calculate on hand, not with fea software.
Also:
1. Matrix [K] for frames is like this: Link is this stiffness matrix the same for all...
