| Summary: | 碩士 === 國立中央大學 === 土木工程研究所 === 100 === The purpose of this study is to observe the behavior of RC beams under cycling loading, which design by standard code. The beams have slab and steel bar cut-off in beam part. Test result will check the beams bar cut-off design according to ACI standard code, but without considering slab bar effect.
From the test result, it was found that the behavior of rectangular RC beam with steel bar cut-off is similar to prototype specimen. The similarity in seismic behavior includes strength, stiffness, and ductility. Both of rectangular beams have the same failure mode at the end of the experiment, concluding as flexural failure at near the column face. This is because, according to the standard design, there are excess stirrups at the end of the steel bar cut-off. Therefore, even the T-beam specimen has extra inducel shear provided by slab bars, there is no harm to the failure mode of the T-section beam, similar to rectangular beams.
