为此对双腹板、顶底角钢半刚性节点的试验数据进行分析，绘出试件各组合件关键点的荷载-应变关系曲线。
Then the experimental data of joints of top and seat angle with double web angle are analyzed and load-strain curves of member subassemblages key points are drawn.
半刚性基层的正应力沿截面高度呈线性分布，合成大梁试件的中性层低于其几何形心。
The results also show the strain is linear distributing along the section height of semi-rigid base, and the neutral layer of the beam specimen is lower than its geometrical center.
