Welded truss joint stiffness
Welded truss joint stiffness
(OP)
I am currently involved with analyzing a truss that has welded joints. An analysis was done assuming the traditional purely pinned joints. A separate analysis was done assuming that the joints were pure rigid connections. From the pure rigid joint solution a bottom truss chord fails the shear-moment interaction check. I would like to perform the analysis using a semirigid connection. My question is what rotational stiffness to use in the analysis. Is there any material available dealing with this particular problem?

If you are designing then it's easiest to stick to either pinned or fixed connections. Whichever you use the construction should use connections of type compatible with the design assumptions.
