摘要
提出了带有端板连接的可替换式耗能梁段的新型偏心支撑结构体系,并且基于ABAQUS有限元分析软件建立了一个带有端板连接的可替换式耗能梁段的单层偏心支撑钢框架有限元模型,研究了这种可替换式偏心支撑钢框架在循环荷载作用下的抗震性能与耗能能力,结果表明可替换式耗能梁段偏心支撑钢框架结构具有较好的耗能能力。
This paper proposed a new type eccentrically braced structural system in which a replaceable shear link specimen was connected to floor beam by end-plate. The finite element model of a one-story eccentrically braced steel frame with an end-plate connected replaceable link specimen was established by software ABAQUS. The seismic performance and energy dissipation of the new type eccentrically braced steel frame under the cyclic loading was analyzed. The numerical results showed that the new type eccentrically braced steel frame with replaceable shear link has better energy dissipation capacity under earthquake load.
