【 摘 要 】
An earthquake resistant structure should be able to perform as expected when it's struck by an earthquake such as it may experience slight damage and should be able to be repaired to its original state when struck by a design level earthquake. However, there are still debates whether reparation should also be viable when structures are experiencing severe damage. There are still a little to no studies about repairing severely damaged structures, therefore a study was made to see how severely damaged structures behaved after being repaired. Two beam column joints are used as specimens, which were severely damaged by an earthquake simulation before getting repaired. Both their initial and repaired condition are then modeled analytically using SAP2000. Their behaviors such as plastic hinges, joint's shear deformation, bond slip, and rebars' residual strain and stress due to previous loading are also implemented to the model. Although the lateral strength of the specimens are similar to their analytical model, the other behavior, especially their stiffness is not similar, therefore needing another parameter implemented in the model.
