Design of non-linear semi-rigid steel frames with semi-rigid column bases
Electronic Journal of Structural Engineering, 2004 This article presents an analysis and design method for steel frames with semi-rigid connections and semirigid column bases. The analysis takes into account both the non-linear behaviour of beam-to-column connections and P-Δ effects of beam-column ...

Effects of Semi-Rigid Connection on Structural Responses
Electronic Journal of Structural Engineering, 2010 There are several idealizations in numerical analysis of structures. In the joints and supports, which is usually assumed to be pinned or rigid, semi-rigid connection should be considered to obtain more realistic, reliable and also economical results ...
