Coupling beams serve as primary source of energy dissipation in coupled shear wall systems during large earthquakes. However, the overestimation of the shear strength of diagonally reinforced coupling beams may be adverse effect on the seismic performance of coupled shear wall systems. In order to f...

구조적 퓨즈란? | 병렬전단벽 (Coupled shear wall)은 독립된 여러 전단벽에 비해 횡력을 효율적으로 저항 할 수 있다. 병렬전단벽 시스템에 큰 지진이 발생했을 때, 적절한 상세의 연결보는 상당한 비탄성 변형을 견디는 “구조적 퓨즈 (Structural fuses)” 역할을 한다. 그러므로, 큰 지진이 발생하는 동안 연결 보는 병렬전단벽 시스템에서 에너지 소산의 주된 역할을 한다 (Paulay and Priestley, 1992)[1]. | |
세장한 연결보의 필요성이 커지는 이유는? | 최근 병렬전단벽 시스템에서 제한된 층고와 건설비용 때문에 세장한 연결보의 필요성이 커지고 있다 (Naish et al., 2009)[10]. | |
