| Özet |
| This paper presents the results obtained from cyclic tests of two identical, almost full-scale buckling restrained braces (BRBs). Fabrication of gusset plates, data of material properties and detailed drawings were provided by the producer. Two specimens (labeled as BRB-1 and BRB-2) with large diameter pinned end connections, and having rectangular core plates with S235-SSE grade steel were used in the tests. Quasi-static reversed cyclic loading tests were carried out. A displacement loading protocol proposed by the Seismic Provisions for Structural Steel Buildings, AISC 341-10 was used for both of the BRBs considered herein. Tested BRBs exhibited satisfactory performance (without buckling) under the assumed loading history (ie the AISC loading protocol). Experimental results show that the BRB specimens reached a maximum drift of 2.74% that corresponds to a lateral displacement of 51.00 mm, while no fractures in the welds or any sign of local or global instability were observed. Equivalent damping ratios (ξeffb) were obtained as 47.49% and 44.68% for BRB-1 and BRB-2, respectively. |
