본 연구에서는 이러한 비선선형동적해석 방법을 사용하여 국내 설계기준에 따라 설계된 철골모멘트저항골조 건물의 연쇄붕괴 가능성을 조사하였다. 예제 건물의 평면은 일반적인 사무실 건물에 사용되는 형태를 사용하였고, 동일한 평면에 대해 층수, 기둥제거위치, 구조시스템, 지진하중 들을 변수로 하여 다양한 건물을 설계하고 해석한 후 그 결과를 비교하였다. |
| 요약2 |
The progressive collapse-resisting capacity of steel moment resisting frames designed by KBC2005 was investigated using a nonlinear dynamic analysis procedure suggested in the guidelines. The frames were designed and analyzed using several parameters such as number of story, structural system, and location of column removal. The results showed that the frames with the same plan shape are susceptible to progressive collapse as the number of story decreases and the location of the removed column moves from inside to outside. Also, frames designed only for gravity load turned out to be more vulnerable to the progressive collapse than those designed for earthquake load. However both systems did not show large difference in the resistance for progressive collapse because the design seismic load is not high enough. |
