dc.description.abstractFEMA 351은 취성파괴를 방지하고 WUF-B 접합부의 보 끝에서 소성 변형이 발생할 수 있도록 연구를 수행하였다. 본 연구에서는 WCPF 접합부의 연쇄붕괴 저항성능을 평가하기 위해 WUF-B 및 RBS 접합부의 평가를 위한 연구를 수행하였다. 대체 경로법은 기둥 손실의 동적 영향을 고려한 에너지 기반 근사 해석을 사용하여 수행되었으며, 구조적 견고성과 민감도를 기반으로 구조물의 연쇄 붕괴 저항 성능을 평가하였다. 이전 연구에서 분석된 WUF-B 및 RBS 접합부와 비교하였을 때 WCPF 접합부는 구조적 견고성이 33% 더 향상되었으며 기둥 하나를 제거할 때 연쇄붕괴에 대한 민감도가 11% 감소한 것으로 평가되었다. 단변방향 기둥 제거 시나리오에서는 WCPF 연결 구조만이 연쇄붕괴 저항성능을 갖는 것으로 나타났다. WCPF 접합부는 WUF-B 및 RBS 접합부보다 연쇄붕괴 저항성능이 더 효율적으로 평가되었다.-
dc.description.abstractFEMA 351 outlines the use of welded cover plated flange (WCPF) connections to prevent brittle fracture and enable plastic deformation atthe beam's end in WUF-B connections. This study assesses the progressive collapse resistance of WCPF connections by applying thealternative path method to a target structure previously examined in the evaluation of WUF-B and RBS connections. An energy-basedapproximate analysis, considering the dynamic effects of sudden column loss, was used to evaluate the structure's progressive collapseresistance in terms of structural robustness and sensitivity. Results were compared with structures featuring WUF-B and RBS connectionsanalyzed in a prior study. The structure incorporating WCPF connections demonstrated a 33% improvement in structural robustness and 11%less sensitivity to progressive collapse when one column was removed, compared to the WUF-B and RBS connections in the previous study. In the scenario of removing two columns, only the structure with WCPF connections exhibited progressive collapse resistance capacity. TheWCPF connection displayed superior progressive collapse resistance capacity compared to WUF-B and RBS connections.-
