| 摘 要： | K形高强钢组合偏心支撑(K-HSS-EBF)是指耗能连梁和支撑采用Q345钢,而框架梁、框架柱采用高强度钢(如Q460)。为研究其在罕遇地震作用下的抗震性能,在试验研究的基础上,采用直接基于位移的抗震设计方法设计了5层、8层和12层算例,分别进行静力推覆分析和动力弹塑性分析,研究高强钢组合偏心支撑钢框架在罕遇地震作用下层间侧移分布和破坏模式。研究结果表明:直接基于位移的抗震设计方法设计的算例在罕遇地震作用下,结构的层间侧移满足我国现行抗震规范的要求,结构呈理想的渐进式梁铰屈服机构,并证明该设计方法的合理性和可靠性。

| Abstract: | Links and braces use Q345 steel, while other structural members use high strength steel (e.g. Q460 steel). In particular, this is used in high strength steel combination eccentrically braced frames (HSS-EBFs), as it improves economic efficiency due to its weight and high strength. In this paper, in order to study their seismic performance, four groups of HSS-EBFs were designed using the direct displacement-based design (DDBD) method and included 5-, 8-, and 12-story structures. Nonlinear pushover analysis and dynamic elastoplastic analysis were performed on all designs, and inter-story drift and failure modes under rare earthquake events studied. The results show that the inter-story drifts satisfy the deformation requirement of the seismic code under rare earthquakes and the K-HSS-EBF structure presents an ideal progressively plastic mechanism, proving that this new design method is reasonable and reliable. |
