| 요약1 |
본 연구에서는 철골모멘트골조 건물을 선택하여 패널존의 변형을 고려할 수 있는 모형화 기법을 이용하여 비선형동적해석을 수행하였다. 이를 통해 패널존 변형 고려 유무에 따른 최대 수직변위 및 소성힌지각의 차이를 조사하였다. 이 때, 지진하중의 고려 여부, 기둥제거 위치 및 층수에 따른 영향도 함께 조사하였다. |

The panel zone deformation is known as a major parameter to affect the nonlinear behavior of steel moment resisting frames under earthquake loads. Especially in weak column-strong beam condition, it is very distinguished. As the strong column-weak beam condition is not specified in the Korean design code, the panel zone deformation may be significant. In this study the effect of panel zone effect on the progressive collapse resisting capacity of steel moment frames was investigated. The results showed that the panel zone deformation of structures designed by the Korean Building Code highly depends on the location of the column removal. According to the analysis results, the panel zone deformation turned out to be very severe if the removed column was located at the bay including an exterior panel zone. On the other hand, the panel zone was not significant if the bay did not include an exterior panel zone. As the number of story increased, the effect of the weak panel zone on the overall behavior decreased regardless of the panel zone strength and the location of the column removed. It was also found that the panel zone deformation had little effect on the overall behavior of structures designed considering seismic load specified in the design code even though the panel zone was not reinforced. |
