Seismic behavior of high strength rc columns
WebFeb 2, 2024 · During an earthquake, columns act as the primary element in resisting seismic forces. The damages of reinforced concrete (RC) frame structures during seismic activities have revealed that the poor performance of columns causes the collapse of the overall frame structure (Ye et al. 2010; Liberatore et al. 2013).Similarly, various structural failures … WebJul 7, 2024 · This paper presents an experimental investigation of the seismic performance of interior beam–column joints with beams reinforced with Grade 600MPa longitudinal steel bars. Six full-scale reinforcement concrete (RC) interior joints are designed with different axial compression ratios and longitudinal reinforcement ratios, which are …
