ABSTRACT
ABSTRACT: As one of the principal deformation indices, the inter-story drift ratio is generally applied to seismic performance assessment of building structures. As for momentresisting frame structures, the inter-story drift (global deformation) is the integration of local deformation of constituent components, such as the beam, column and joint. In this study, nine half-scale Reinforced Concrete (RC) beam-column subassemblages extracted from a moment-resisting frame structure were tested under cyclic loading to study the relationship between the global deformation and the local deformation. The main design parameters of the tests are the amplification coefficient of column moment, the axial compression ratio, and the shear-span ratio of beam. The individual contribution to the inter-story drift from the beam, column, and the joint was analyzed from the test data. The results obtained in this study can be incorporated into displacement-based seismic design of RC frame structures.
