초록

The objective of this research is to provide better knowledge on the structural behavior of strong axis H beam bracket type SRC column-RC beam joint, supported by experimental results, that can be broadly applicable to many structures with similar characteristics. For this purpose, literature reviews and field survey were performed to classify the most commonly used for this type of joints. Then, experimental program was designed and performed with 5 SRC column-RC beam joint specimens designed with long and short bracket type details. Using the experimental results obtained from the testing of these specimens, structural performances of the joints such as the hysteretic curves, the maximum strength capacities, the strains of reinforced bars were investigated. From the test results, reinforced bracket type specimens revealed to have the strengths close enough to the nominal strengths. The un-reinforced long bracket type specimen showed brittle fracture resulting in lower strength capacity due to the shear ruptures near the hinges at the end of the beams. Regardless of the reinforcement at the end of the beam, short bracket type specimens revealed to possess the strength capacities close to the nominal strengths, however, reinforced specimen showed more ductile behavior after maximum strength capacity reached.
