기존 RC 기둥 부재의 이력거동 예측을 위한 비선형 해석모델 = Nonlinear Analysis Models to Predict the Hysteretic Behavior of Existing RC Column Members

다국어 초록 (Multilingual Abstract)

The recent earthquake in Korea caused a lot of damage to reinforced concrete (RC) columns with non-seismic details.
The nonlinear analysis enables predicting the hysteresis behavior of RC columns under earthquakes, but the analytical model used for the columns must be accurate and practical. This paper studied the nonlinear analysis models built into a commercial structural analysis program for the existing RC columns. The load-displacement relationships, maximum strength, initial stiffness, and energy dissipation predicted by the three analysis models were compared and analyzed. The results were similar to those tested in the order of the fiber, Pivot, and Takeda models, whereas the fiber model took the most time to build. For columns subjected to axial load, the Pivot model could predict the behavior at a similar level to that of the fiber model. Based on the above, it is expected that the Pivot model can be applied most practically for existing RC columns
