Influence of splices on the stability behaviour of columns and frames
Simão, Pedro D.; Coelho, Ana M. Girão; Bijlaard, Frans S. K.The paper presents a study on the influence of splice connections on the stability behaviour of compressed steel columns. The column is modelled as two independent prismatic parts connected by a rotational spring at the splice location and rotational and extensional springs at the column ends to represent the effect of the adjacent structure. The general behaviour is characterized using a polynomial Rayleigh-Ri...
Experimental assessment of the ductility of extended end plate connections
Coelho, Ana M. Girão; Bijlaard, Frans S. K.; Silva, Luís Simões daAn experimental investigation of eight statically loaded extended end plate moment connections was undertaken at the Delft University of Technology to provide insight into the behaviour of this joint type up to collapse. The specimens were designed to confine failure to the end plate and/or bolts without development of the full plastic moment capacity of the beam. The parameters investigated were the end plate ...

Coelho, Ana M. Girão; Bijlaard, Frans S. K.; Gresnigt, Nol; Silva, Luís Simões daThe results of 32 tests on bolted T-stub connections made up of welded plates are presented and discussed. Although T-stubs have been used for many years to model the tension zone of bolted joints, the research was mainly concentrated on rolled profiles as T-stub elements. To extend this model to the case of welded plates as T-stub elements, a test programme was undertaken at the Delft University of Technology ...
