Abstract:

Buckling restrained braced frames (BRBF) have been wildly used as an efficient seismic load resistant system in recent years mostly due to their symmetric and stable hysterical behavior and significant energy absorption capacity. this research tried to study about different energy absorbing when spaces are changed. the spaces between core and cases are changed from 1mm to 5mm and gaps between core and fillers are changed from 3mm to 40mm. In finally we achive that gaps are so effective and materials properties make huge diffrent in energy absorbed in BRBF s. the most diffrent energy absorbed appear when gaps between case and core are changed. The tests done by Tabatabayi et al. in Tehran University chose between many eligible researches because this examinations were newer and comprehensive than other researchs.
