| Research Abstract |
To improve the seismic performance of the joints connected steel member with reinforced concrete member in series and orthogonally, the joint details using perfobond plate connectors were proposed. In case of the joint connected steel member with reinforced concrete member in series, holes were drilled in the steel flanges of the embedded steel member. On the other hand, In case of beam-column joint, perfobond plate connectors were attached on the flanges of the embedded steel beam. From the test results, it was shown that maximum strength of the joint with perfobond plate connectors increased compared with that of the joint without perfobond plate connectors and large degradation was not observed after maximum strength.
Based on the stress transferring mechanism and resistance mechanism of the joints proposed by authors, the design formulae of joints with perfobond plate connectors were proposed. The predictions were shown to be in good agreement with the test results.
