| Research Abstract |
Loading test of circular CFT column-H shaped beam connection was carried out. Test parameters are diameter thickness ratio of column skin plate, presence or absence of infilled concrete, scallops and floor slabs. The effect of test parameters on maximum strengths was not remarkable when there were not slabs. On the other hand, for test specimen with floor slabs, the maximum load of specimen with non-scallops is 50kN greater than that of specimen with scallops. The effect of out-of-plane deformation is larger in the specimen with scallops considering that the yield area of beam web subjected to tensile stress is smaller and the strain of the column skin plate is larger.
