摘要
建立T形加劲肋节点、矩形加劲肋节点、加强板螺栓节点三维非线性有限元模型,采用有限元方法对3种节点在单调加载下的力学性能进行研究,模拟分析了单调加载时节点的受力性能、承载性能,以及节点的应力分布和破坏模式,并得出轴压比等因素对节点受力性能的影响。
The three-dimensional nonlinear finite element model of T-stiffener joint, square stiffener joint and strengthening bolt joint were established. The finite element analysis method was used to study the mechanical properties of three kinds of joints under monotonic loading,simulated and analyzed the mechanical properties and bearing capacity of joints,the stress distribution and failure modes of the joints,and the influence of the axial compression ratio on the mechanical properties joint was obtained.
