Loading Capacity and Rotational Performance of Radial Spherical Plain Bearing Joints
以上海体育场钢屋盖改造为工程背景,研究了向心关节轴承节点性能.首先,进行了在竖向压力作用下的节点承载能力和转动性能试验,掌握了节点的极限承载力和应变强度发展规律,并提出了节点转动摩擦系数的计算方法及其数值.其次,应用ABAQUS开展了有限元数值分析,进一步研究了节点的破坏模式和受力性能.研究表明向心关节轴承节点在压力工况下具有良好的承载能力和转动性能,能实现钢结构空间节点完全铰接的功能.
The performance of radial spherical plain bearing joints is investigated in this paper,based on the engineering background of steel roof renovation of Shanghai Stadium.First,tests on bearing capacity and rotational performance of the joint were performed under vertical compressive force.Both the ultimate bearing capacity and the strain intensity development feature were grasped.A method for calculating rotational friction coefficient and its value of the joint were proposed.Next,finite element numerical analysis was conducted using ABAQUS to further study the damage mode and mechanical behavior of the joint.It is found that the radial spherical plain bearing joint has good load carrying capacity and rotation performance under compressive condition,and achieves the function of fully hinged space node of steel structures.
