Abstract

The objective of this research is to evaluate the seismic performance of steel intermediate moment frames(IMFs) with different heights. The seimic performance is conducted according to ATC-63. Three-, six, nine- and twelve-story IMFs are designed according to KBC 2009. The connection is modeled to have a drift capacity of 0.02rad, which is required for IMF connections. This study shows that the probability of collapse increases with an increase in the height of the frame. Nine- and twelve-story frames did not satisfy the requirement specified in ATC-63.

본 연구의 목적은 다양한 높이에 따른 철골 중간모멘트골조의 내진성능을 평가하는 것이다. 구조물의 내진성능은 ATC-63에서 제안한 방법론에 따라 평가되었다. 3층, 6층, 9층, 12층 중간모멘트골조의 설계는 KBC 2009에 따라 수행하였다. 접합부의 모델링은 철골 중간모멘트골조에서 요구되는 회전성능인 0.02rad을 만족하도록 모델링하였다. 연구를 수행한 결과, 구조물의 붕괴확률은 높이가 증가함에 따라 증가하였다. 특히 9층과 12층 구조물은 ATC-63에서 제시한 요구조건을 만족하지 못하였다.
