Abstract

Recently, use of the precast concrete (PC) system, which can increase economy by minimizing field work, has rapidly increased. However, the PC system cannot exhibit structural performance under construction, specifically before integration between members. Furthermore, since it is difficult to secure the structural integrity of beam-column joints even after construction, the PC system is vulnerable to progressive collapse. In the PC system, various types of details for PC beam-column joints have been proposed, while the structural/construction details of PC system generally used in Korea differ from those of overseas PC systems. However, studies on the progressive collapse of the domestic PC system are limited. Thus, in this study, we investigated the structural/construction details of PC beam-column joints mainly used in Korea. Based on the investigation, for the prototype PC system with typical joint details, a nonlinear finite element analysis was carried out to evaluate its structural performance under progressive collapse. Further, a parametric study was performed, and the effect of the design parameters was investigated, to recommend a method to improve the progressive collapse resistance of the PC system.

최근 현장작업을 최소화할 수 있는 PC(Precast Concrete) 건축공법의 적용이 급속하게 활성화되고 있다. 그러나 PC 공법은 시공 중, 특히 부재간 일체화 이전에 구조적 성능을 발휘하기 어렵고 완공 후에도 접합부의 일체성을 확보하기 어려워 연쇄붕괴에 취약하다. PC 건축물에서는 다양한 PC 부재간 접합 상세가 존재하며, 국내외 구조/시공 상세가 현격히 다르다. 그러나 국내 PC 시스템의 시스템과 상세 특성을 반영한 연쇄붕괴에 대한 연구는 매우 미비하다. 따라서, 본 연구에서는 국내에서 주로 사용하는 PC 구조시스템과 접합부 구조/시공 상세를 조사 분석하였다. 이를 기반으로 국내에서 사용되는 전형적인 PC 시스템의 유형을 설정하고 상기 PC 시스템의 연쇄붕괴방지성능을 평가하기 위하여 비선형 유한요소해석을 수행하였다. 해석결과를 바탕으로 국내에서 주로 사용된 PC 구조시스템의 연쇄붕괴방지 성능을 평가하고 구조설계시 고려사항을 제안하였다.
