| Research Abstract |
The proposal consists of BRBs in adjacent stories that share the same gusset plate, which is fastened to the concrete beam-to-column joint by prestressing bolts and is kept by a pair of RC corbels. The behavior of the BRB connection and the whole building was observed through an experimental test and followed by analysis. First, the cyclic performance of the connection of the proposed continuously braced frame system is examined through subassembly test. As a result, the effectiveness of this connection method was confirmed. Next, the shear strength of RC corbels and force transmission in stirrups and concrete are investigated by component test and finite-element analysis. In addition, a strut-and-tie model is proposed to estimate the shear strength of deep corbels. Finally, seismic response analysis of reinforced concrete building with BRBs was carried out and the dynamic performance wasconfirmed.
