| Özet |
| Buckling Restrained Braces (BRBs), display a balanced hysteretic behavior by axial yielding under reversed cyclic tension and compression forces. Although component testing of BRBs is conducted under various symmetrical cyclic displacement loading protocols, the use of unsymmetrical protocols in testing to account for near-fault effects of ground shaking are quite limited. To investigate the performance under such a loading, one full scale steel-core BRB specimen (named as TURKBRACE BRB-SC1) with simple details has been designed to AISC specification, fabricated, and cyclically tested. TURKBRACE BRB-SC1 exhibited excellent performance under fatigue and near-fault loading histories. Experimental results show that the BRB specimen reached a maximum drift of 6%, while no fractures in the welds or any sign of local or global instability were observed. Hysteretic curves, behavioral values such as maximum strength in tension and compression cycles, stiffness changes with displacement cycles, hysteretic damping, and cumulative hysteretic energy dissipation values are given. |
