摘要
组合结构中,框架柱或剪力墙由于其内设置有较大尺寸的型钢,与之相连的型钢梁纵向钢筋常无法有效锚固于型钢梁柱或剪力墙节点。结合某具体超高层项目提出了一种保证此类组合结构节点的可靠锚固的节点设计构造,并选取该工程中某代表性节点,采用有限元软件Abaqus重点考察了特定工况下该节点的受力特性,在设计荷载作用下节点处各材料的最大Mises应力值均不大于材料的强度设计值;型钢梁部分区域及靠近剪力墙型钢梁内第一根箍筋的应力水平较大,设计时应予以重点加强。
In the composite structure,the frame column or shear wall is provided with a section steel of a larger size in it,and the lon‐gitudinal reinforcement of the section steel beam connected with it often cannot be effectively anchored to the section steel beam column or shear wall node.In this paper,a joint design and construction to ensure the reliable anchorage of such composite structure joints is proposed in combination with a specific super high-rise project,and a representative node in the project is selected,and the finite element software Abaqus is used to focus on the mechanical characteristics of the node under specific working conditions,and the maximum Mises stress val‐ue of each material at the node under the design load is not greater than the strength design value of the material.The stress level of the first stirrup in some areas of the section steel beam and the steel beam close to the shear wall is larger,and it should be strengthened in the design.
