Abstract

Nowadays, short-medium span steel-concrete composite I-girder bridges (SCC) are very popular, owing to their short construction time and reduced costs. Their limited weight makes their use adequate also for seismic areas, even though their seismic behaviour has not been yet adequately investigated. With this aim, within the European project (SEQBRI), the seismic behaviour of new pier-to-deck connections entailing the use of concrete cross-beams (CCB) has been recently studied. This paper shows the results of a comprehensive experimental investigation on this kind of connections conducted with the aim of characterizing the hysteretic behaviour and calibrating a component-based model for seismic analysis. Three different type of connection have been tested: one designed according to the standard DIN-FB104, generally utilized for gravity loads only, and other two, proposed for bridges located in low and medium intensity seismic prone areas. Based on different resistant mechanism, these latter have demonstrated a good behaviour in terms of strength and ductility.
