Continuous beam models with spring supports were set up to model end-plate connections. By comparing the results from tests with those from model analysis, the following conclusions can be drawn: during loading process, the neutral axis moves from the centroid axis to compression zone, not exceeding the center line of bolts inside the compression flange; ultimately, the tension flange and end-plate can be simplified as T-stub on the assumption that the axial forces of bolts in tension zone are equal to each other.

理论计算系建立带弹性支座的连续梁模型模拟端板连接，将模型计算结果与试验结果比较分析，结果表明：加载过程中，螺栓群中和轴逐渐从其形心轴向受压区移动，但不超过受压翼缘内侧螺栓中心线；极限状态下，受拉翼缘和端板可简化为等效T型件。
