| Abstract |
This study aimed to evaluate the seismic performance of deep steel beams with rectangular openings. Test results showed that beam flange
yielding was initially observed at a 1.5% story drift ratio, and this was followed by web yielding at a 2%~3% story drift ratio for most
specimens. Then, beam flange buckling was observed at 3%~4%, followed by lateral torsional buckling. All specimens were tested until they
reached a 6% story drift ratio, and at this stage, beam flange fracture was observed for specimens with a single rectangular opening.
Normalized moment and total plastic rotation of beams with double rectangular openings showed a higher capacity when compared with those
of solid specimens. All specimens were found to have the seismic performance of Special Moment Frames as specified by the steel structure
