Abstract

본 연구에서는 2경간 합성바닥슬래브의 기여도를 반영하여 철골모멘트골조의 연쇄붕괴저항성능의 더욱 정확한 평가를 위해 사용할 수 있는 개선된 에너지기반 비선형정적 해석법을 제시하고자 한다. 이를 위해, 우선 재료적/기하학적 비선형 유한요소해석을 수행하여 2경간 합성바닥슬래브의 거동을 살펴보았다. 2경간 합성바닥슬래브의 변형형상을 이상화하여 에너지기반 해석을 위한 근사모델을 개발하였다. 제안모델은 기둥제거 시나리오하에서 2경간 합성바닥슬래브의 일방향 축인장력 및 변형에너지응답을 모델링하는데 쉽게 이용할 수 있음을 보여주고 있다.

In this study, an improved energy-based nonlinear static analysis method are proposed to be used for more accurate evaluation of progressive collapse potential of steel moment frames by reflecting the contribution of a double-span floor slab. To this end, the behavior of the double-span floor slab was first investigated by performing material and geometric nonlinear finite element analysis. A simplified energy-absorbed analytical model by idealizing the deformed shape of the double-span floor slab was developed. It is shown that the proposed model can easily be utilized for modeling the axial tensile force and strain energy response of the double-span floor slab under the column-removal scenario.
