| Outline of Final Research Achievements |
Firstly, a series of cyclic loading tests of exposed column base under tri-directional loads was conducted and the analytical model to simulate 3D behavior of exposed column base was validated based on comparing with the test results. And, the influence of inelastic behavior of exposed column bases to damage distribution of steel frames was evaluated through a series of earthquake response analyses of steel moment-resisting frames (MRFs) using plane frames. Moreover, since buildings may be subjected to one or more severe foreshocks and/or aftershocks within a short period, this study performed a series of earthquake response analysis of MRFs subjected to multiple strong earthquake ground motions and presented how the damage to structural components accumulate.
