摘要
Abstract
In this study,nine half-scale reinforced concrete (RC)beam-column sub-assemblages extracted from a moment-resisting frame structure were tested under cyclic loading to study the relationship between the global de-formation and the local deformation.The main design parameters of the tests are the amplification coefficient of col-umn moment,the axial compression ratio,and the shear-span ratio of beam.The study indicates the relationship between the inter-story drift and the local deformation of structural member is related with the damage pattern of the specimen.For the specimens with the flexural failure of beam ends,the inter-story drift caused by the shear de-formation of the joint is very small so that the shear deformation of the joint could be omitted during the elasto-plas-tic earthquake response analysis of frame structures.For the specimens with the flexural failure of the beam or col-umn ends and the shear failure of the joint,the inter-story drift caused by the shear deformation of the joint is sig-nificant so that the shear deformation of the joint could not be omitted during the elasto-plastic earthquake response analysis of frame structures.关键词
