ABSTRACT
The study of seismic behaviour of the composite steel-concrete structures is of a special interest in regions of high seismicity. Works in this field was started in Japan and in North America. Recent works in the same field has been done also in Europe (Office for Official Publications of the European Community 1992, Abed and Plumier 1993, Plumier and Schleich 1993, Elnashai et al. 1991). However, significant gaps in the knowledge remain, to which corresponds a lack in design rules for composite steel-concrete structures. Consequently, to fill some of the gaps mentioned above, researchs on seismic behaviour of composite structures have been realised, with an active participation of the University of Liege.Tests have been earned out on composite beam-column specimens under cyclic loads, aiming at a better knowledge of the connection behaviour in general and of the influence of concrete with respect to the behaviour of pure steel components.
