摘    要:D型偏心支撑钢框架是偏心支撑结构中常用的一种抗震耗能结构形式,但是其耗能梁段与柱直接相连,为了满足强柱弱梁节点更强和梁端抗弯承载力的设计要求,一般需要对梁柱连接节点处采取一些加强措施。针对传统节点加强措施存在的不足,提出一种新型剪切型耗能梁段与柱连接节点——加肋板方案。给出了设计方法,利用ANSYS有限元分析程序,采用Shell143壳单元建立了有限元分析模型,将该新型梁柱连接节点与梁柱直接相连的D型偏心支撑结构进行了理论分析比较。验证了新型节点不仅可以使剪力远离翼缘焊缝,而且可以放松钢柱对梁翼缘端部的局部变形约束,并可排除耗能梁段与柱邻近区域的屈服。

关 键 词:D型偏心支撑  耗能梁段  肋板  壳单元  有限元

Abstract:The D-type eccentrically braced steel frame which the link connect column provides an efficient structural system for resisting seismic activity. Some reinforced connection between beam and column should be taken for meeting the design demand. This paper advances a new connection protocol (adding rib) between shear links and column. This paper provides the design measure and the data for eontrastive finite element analytical study between the new protocol and link-to-column connections. Results indicate that the new protocol may draw shear force away from link flange welds, relax the extreme local deformation in the link flanges near the column face, and preclude yielding in the link in the region adjacent to the column.
Keywords:D-type eccentrically-braced steel frame link beams rib shell element finite element
