翼缘削弱型外伸式端板连接节点在梁柱弱轴方向的受力性能研究

Study on Behavior of Extended End-plate Connection Joint with Reduce-beam Section in Beam-to-column Weak-axis Direction

通过ANSYS有限元程序,对翼缘削弱型端板连接节点进行了单调加载和低周反复荷载作用下非线性有限元分析,研究翼缘削弱型端板连接节点的破坏形式和受力性能。分析结果表明:在梁柱弱轴方向,翼缘削弱型端板连接具有较大的连接刚度和理想的滞回性能;梁翼缘处的焊缝强度是决定翼缘削弱型端板连接节点性能的主要因素,这为翼缘削弱型节点的研究和应用提供了理论依据。

The authors present a nonlinear finite element analysis of end-plate connection with reduce-beam section by applying monotonous load and cycle load in ANSYS,and study the form of damage and behavior of this type connection.The analysis results indicate that end-plate connection with reduce-beam section can have great connection stiffness and perfect hysteretic behavior in beam-to-column weak-axis direction,and weld strength at beam flange is a main factor of influencing the connection behavior,which provides theory gist for research and application of this type connection.
