FEM for Space frame one beam is Pinned at its Local Y axis
FEM for Space frame one beam is Pinned at its Local Y axis
(OP)
Hello Everyone.. I have a problem for the space frame direct stiffness method .. If one of the beam is pinned at one end(eg. @ local y axis only), does this mean that the stiffness matrix of this beam would be written differently from other beam elements..
I am currently making a software and I tried to make some modifications on the stiffness matrix for the beam that is pined at one end.. it seemed to work.. but I would like to make sure if my solution is correct..because there may be a better way.
see the figure below for clarifications

It should give you what you want.
By the way, we aren't supposed to put the same question in more than one thread.
