| Abstract | The column bases at ground level in self-centering steel moment resisting frames (SC-MRFs) may suffer damage by plastic hinging under the Design Basis Earthquakes (DBE). The formation of plastic hinges at column bases may hinder the self-centering behavior of the SC-MRF. In this research, in order to eliminate damage at column bases and enhance the self-centering capability (i.e., negligible residual drift) of the SC-MRF, a post-tensioned column base connection is proposed. The feasibility of using post-tensioned column base connections in the SC-MRFs was investigated for a 6story, 4-bay office building in the Los Angeles (LA) region by nonlinear static and dynamic analysis. Based on the analysis results, it was found that if the shear resistance is provided properly, use of the post-tensioned column base connection in the SC-MRFs results in self-centering behavior at column bases and elimination of damage in columns under the DBE. |
