FUSEIS bolted and welded beam splices
These splices were also developed during the RFCS-supported FUSEIS project [10-12]. They may be employed in moment resisting composite frames, where the beam sections act compositely with the concrete slab. The continuity of the beams is interrupted and then restored by steel cover plates that connect the web and the lower flange of the beams (Fig. 3). The steel cover plates may be bolted or welded to the beam. The cross section at the beam splice is weaker so that energy dissipation and damage concentrate on the cover plates which can be easily and quickly replaced. The spliceswere developed and investigated both experimentally and analytically at POLIMI Milano and IST Lisbon.
