Abstract

The first paper of continuing two papers observed that the one of most important factor of determining collapse capacity is plastic deformation capacity of column. This study investigated the plastic deformation capacity satisfying collapse prevention level in maximum considered earthquake. For this purpose, incremental dynamic analysis was performed with the prototype structure introduced in former paper using 40 ground motion records. The Collapse capacity was evaluated with confidence factor method of FEMA355F and methodology of FEMA-P695.

Key Words: Collapse capacity; Plastic deformation capacity; Incremental Dynamic Analysis; Steel intermediate moment resisting frame

요지

연속하는 두 논문중 첫 번쩨 논문에서 도출한 철골중간모멘트골조의 붕괴성능에 가장 큰 영향을 미치는 요인중 하나가 기둥의 소성변형능력이라는 점에 주목하여 최대급지진에서 붕괴방지성능을 만족시키는 기둥의 소성변형능력을 규명하고자 한다. 이를 위해서 첫 번쩨 논문에서 소개한 세 개의 표본건물을 이용하여 40개 지진파에 대한 증분동적해석을 수행하였고 FEMA355F의 신뢰도계수법과 FEMA-P695의 방법론을 이용하여 붕괴성능을 평가하였다.
