Abstract: SRC column-RC beam joint is frequently used for the construction of underground structure in the Top-Down construction method. Various types of joint details have been proposed and implemented for the anchorage of the reinforcing bars. The types can be classified by anchoring methods as follows: (1) passing through type; (2) wing plate type; and (3) H-beam bracket type. Although these types are widely used in Korea, the structural performance is not clearly understood.
For each type of joint, the structural characteristics such as strength, stiffness, energy dissipation capacity, stiffness degradation, and ductility under monotonic and cyclic loads were tested. The test results showed that the passing through type has the best structural performance.
By advancing the passing through type, the wide beam type specimens were experimentally investigated for the field application. The wide beam type uses a number of reinforcing bars that are placed at the edge of the slab not to intersect a steel column without changing its sectional shape. It is concluded that the wide beam type is adequate in the SRC column-RC beam joint not only for its structural capacities, but also for its economic merits.
