DUAREM replaceable bolted link
DUAREM replaceable boltedlink was developed and studied experimentally and analytically by UPT Timisoara in a Romanian research project. Additional experimental tests were performed at the ELSA Laboratory at JRC Ispra during a European FP7 SERIES project[13-15]. The system consists of short links that are bolted to the floor beams in eccentric braced frames (Fig. 4). They are employed in dual frames consisting of moment resisting frames and eccentric braced frames. The design is such that energy dissipation concentrates at the linkswhich can be removed when damaged. The moment resisting frame acts as a second line of defence that provides the potential for re-centring (straightening) after the seismic event.
