The non-linear behaviour of multiplanar tubular txjoints subjected to in-plane bending moments on the in-plane and out-of-plane braces

摘要

Since no experimental data are available for multiplanar TX-joints subjected to in-plane bending moments, numerical parameter studies have been carried out on multiplanar TX-joints loaded by in-plane bending moments on the in-plane and out-of-plane braces. The effects of the geometrical parameters #beta# and 2#gamma# as well as the moment ratio between the in-plane bending moments on the out-of-plane and in-plane braces have been determined. Finally, based on the FE results, ultimate strength equations have been established describing the interaction effects due to in-plane bending moments on the in-plane and out-of-plane braces.
