Finite element analysis of end-plate connection under seismic loading

The bolted end-plate connection was chosen as an important type of beamcolumn connections for its complexity in the analysis and behaviour due to the amount of connection element and their inheritable non-linear behaviour. A great deal of experiments and earthquake disasters have shown that semi-rig...
