| Özet |
| Aluminum alloy BRBs could be preferable in new buildings or bridges where severe corrosion effects are expected. BRBs can also be used in existing steel or reinforced concrete frames for seismic retrofit purposes to achieve the required strength, stiffness, and ductility. To the best knowledge of the authors, aluminum alloy core and outer tube BRBs having specific details developed in this study are designed, produced, and cyclically tested for the first time in this area. Two aluminum alloy, almost full-scale BRB specimens (TURKBRACE BRB-AC1 and TURKBRACE BRB-AC3) use rectangular plates as the core material made of A5083-H111. The core is surrounded by an aluminum square tube infilled with a high strength grout as the buckling restraining system. Both bolted (weld-free) and welded end connections are used. Experimental results show that, cumulative energy dissipation can be significantly increased when weld-free BRBs are tested. The fabricated BRBs achieved the desired behavior while no global buckling occurred under inelastic displacement cycles. Compared to steel core BRBs, relatively symmetrical hysteretic curves are obtained in aluminum alloy core BRBs. As a result, aluminum alloy core BRBs with special details developed herein showed promise for use in new buildings/bridges or as a retrofitting technique in buildings/bridges that lack strength, stiffness, and ductility. |
