摘要
建立了端板连接节点的有限元模型,并对模型进行了校正。对传统T形件连接强度模型作了修正,建立了端板连接节点的端板强度模型。提出了节点处梁端截面应力分布的两个假设,给出了端板屈服弯矩的近似计算方法。
A finite element model of end-plate connection was established by using ANSYS programs and the validity of the model was confirmed. A strength model of end-plate was presented by modifying the strength model of the T-stub which was set up by Kulak in 1987 and by presenting two hypotheses about the stress distribution on the beam section located at the connection of beam and end-plate.
